What is Isooctyl Thioglycolate Used for

Isooctyl Thioglycolate is mainly used as a specialty chemical intermediate in polymer and plastic industries. Its reactive thiol group and excellent compatibility with organic systems make it valuable for PVC stabilizer production, polymerization control, and other chemical formulations.

1. PVC Heat Stabilizer Intermediate

Isooctyl Thioglycolate is widely used as an important intermediate for producing organotin and metal thioglycolate stabilizers. These stabilizers help improve the thermal stability of PVC products during high-temperature processing by reducing polymer degradation and discoloration.

It is commonly applied in:

  • PVC profiles and pipes
  • PVC sheets and films
  • Plastic processing additives
  • Other heat-resistant PVC formulations

2. Chain Transfer Agent for Polymerization

Due to its active thiol (-SH) group, Isooctyl Thioglycolate can act as a chain transfer agent in free-radical polymerization processes. It helps control molecular weight and polymer structure, improving consistency during the production of polymers and resin materials.

Typical applications include:

  • Acrylic resin production
  • Polymer modification
  • Adhesive and coating formulations

3. Specialty Chemical Intermediate

Isooctyl Thioglycolate is also used as a versatile intermediate for synthesizing other sulfur-containing organic compounds and specialty additives. Its stable ester structure and reactive sulfur group make it suitable for customized chemical formulations and industrial applications.

FAQ of Isooctyl Thioglycolate

Yes. It is classified as Aquatic Acute 1 (H400) and Aquatic Chronic 1 (H410) according to GHS classifications, meaning it is very toxic to aquatic life with long‑lasting effects. Spills should be contained and never released into drains or waterways.

Isooctyl Thioglycolate is insoluble in water but highly soluble in organic solvents such as ethanol, ether, and other common organic solvents. This property makes it suitable for solvent‑based formulations and organic synthesis applications.

For standard 200kg drums, lead time is typically 7–14 days after order confirmation. For IBC containers (1,000kg) or custom packaging, lead time may be 15–20 days. Expedited options are available upon request. We ship from major China ports with full dangerous goods documentation.

Yes. We offer full documentation support, including CoA (Certificate of Analysis), MSDS (Material Safety Data Sheet), TDS (Technical Data Sheet), and regulatory compliance information to assist with local registration in your market.
