Isooctane

Manufacturer Credibility & Facility Snapshot

Shandong Yingtai Chemical (Shandong Wintex Chemical Co., Ltd.) is based in Dongying, Shandong, where it carries out research and development, production and sales of fine chemicals.

The company works from park-based facilities equipped with modern plants, intelligent control systems and integrated utilities. That combination is the profile of a producer running its own process lines and utilities, rather than a trading office reselling third-party material under its own label.

Isooctane is manufactured using advanced petroleum refining isomerization processes or chemical synthesis methods, then released with high saturated hydrocarbon content, extremely low levels of sulfur and olefin impurities, and excellent stability. The stated purpose of the business is straightforward: fine chemicals with customized solutions and full-process after-sales support.

Dongying, Shandong Production base located inside a chemical-industry park with shared utilities and services.
R&D + Production + Sales Full-chain fine chemical operations rather than a single-stage reseller.
Intelligent Control Modern plants, automated process control systems and integrated plant utilities.
≥99.5% Purity Industrial and analytical grades released from the same production base.
1 Feedstock & Route Selection of the refining or synthesis route appropriate to the target grade.
2 Isomerization / Synthesis Advanced petroleum refining isomerization processes or chemical synthesis methods.
3 Intelligent Process Control Modern plants with control systems and integrated utilities for run-to-run consistency.
4 Batch review & Export Packing Documented release, then packing in the format agreed at quotation.

Scenario-to-Specification Decision Guide

Each application below pairs a documented property of isooctane with the grade to specify and the point to confirm before ordering.

Gas chromatography solvent & standard

The high-purity grade is widely used as a solvent and standard in gas chromatography analysis, and isooctane works as an excellent non-polar solvent.

Specify Analytical Grade, ≥99.5% purity, supplied with a batch COA.

Industrial cleaning, extraction & reaction media

Isooctane is insoluble in water and serves as a non-polar solvent for extraction, reaction media and cleaning duties.

Specify Industrial Grade in drums, IBC tanks or Flexitanks, with the packing format fixed at RFQ.

Octane rating & knock testing

Isooctane is the benchmark substance for anti-knock performance and its octane number (RON) is defined as 100, blended with n-heptane (octane number 0) in rating test engines.

Specify Analytical Grade with the reference documentation your test house requires.

High-octane gasoline blending

Isooctane is a crucial component of high-octane gasoline such as 95# and 98#, and an additive in automotive and aviation gasoline to improve anti-knock properties.

Specify Industrial Grade by the container load, and confirm the volume and delivery schedule in advance.

Organic synthesis feedstock

Isooctane is used as a starting material for organic synthesis, including the production of isooctanol and isooctanoic acid.

Specify Industrial Grade with an agreed impurity profile and container type.

Blending, storage & safety planning

Flash point −12 °C: isooctane is a highly flammable liquid and its vapors can form explosive mixtures with air.

Specify Explosion-proof handling and storage with the SDS reviewed before the goods arrive on site.

Sourcing Terms & Packaging Options

Commercial terms are quoted per product. Use these as the baseline for budgeting, then confirm the final figures at RFQ.

Minimum order

One 20'FCL per product

The stated MOQ is one 20-foot container per product, which sets the natural entry point for a first trial order.

Samples

Free of charge

Samples are supplied free of charge; express shipping costs are the customer's responsibility.

Payment

TT and LC

Telegraphic Transfer and Letter of Credit are the primary payment terms; other arrangements can be negotiated.

Discounts

Negotiated by volume

Discounts are available and are negotiated based on order quantity, so quote your annual volume with the enquiry.

Lead time

Within 14 working days

Shipment is generally arranged within 14 working days after receiving the deposit or the original Letter of Credit.

Packaging

Drums to ISO tanks

Steel drums, plastic drums, IBC tanks, Flexitanks, ISO tanks and bags. The right format for industrial or analytical grade is confirmed at RFQ.

Quality Verification & Compliance Documents

Ask for the same evidence set every time so that batch one and batch ten arrive with comparable documentation.

  • COA and SDS — request the Certificate of Analysis and Safety Data Sheet with every batch quotation.
  • Previous SGS test reports — review reference third-party reports for the grade you intend to buy.
  • SGS on-site inspection before loading — arrange third-party inspection at the plant prior to container loading.
  • Low sulfur and olefins — the product is described as having extremely low levels of impurities such as sulfur and olefins.
  • High saturated hydrocarbon content — supports the stability needed for solvent and fuel-testing duties.
  • Batch consistency — ask the supplier to explain how run-to-run consistency is controlled and documented.
  • Explosion-proof handling and storage — a highly flammable liquid whose vapors can form explosive mixtures with air; store cool, well-ventilated and away from ignition sources.
How do I obtain the COA and SDS?
Request them together with your quotation, or order a free sample first. Documents are issued per batch, so confirm that the COA you receive matches the batch number printed on the container labelling.
What is the SGS inspection option?
Buyers can refer to previous SGS test reports or arrange an SGS on-site inspection before loading. The on-site route gives you an independent check on the material actually being loaded into your container.
Why do sulfur and olefin levels matter?
Isooctane is released with high saturated hydrocarbon content and extremely low levels of impurities such as sulfur and olefins, together with excellent stability. Lower impurity levels protect sensitive analytical work and reduce the risk of interference in fuel and synthesis applications.
What storage conditions are required?
Isooctane is a highly flammable liquid and its vapors can form explosive mixtures with air. Handling and storage must take place in cool, well-ventilated, explosion-proof environments away from ignition sources and heat, using explosion-proof equipment and tools.

Supplier Qualification Checklist: Manufacturer vs Trader

Run through these seven checks before you commit a container order. They separate a production base from a brokered supply chain.

  • Production base — can the supplier name the plant location and the park it operates in?
  • Process control — modern plants, intelligent control systems and integrated utilities.
  • Documented review — COA and SDS issued per batch on request.
  • Third-party inspection — SGS reports available, plus on-site inspection before loading.
  • Sample policy — free samples with express shipping paid by the customer.
  • Export packaging — steel drums, plastic drums, IBC tanks, Flexitanks, ISO tanks and bags.
