Description
Tert-Amyl Alcohol (CAS 75-85-4), also known as tert-Pentanol, Amylene Hydrate, and T-Amyl Alcohol, is a tertiary aliphatic alcohol with molecular formula C5H12O. It carries no assigned E-code and is classified under HS code 29051500 within the Alcohols & Glycols category.
In food and fragrance applications, it functions as a flavorant and aroma carrier, where its tertiary structure resists oxidation and supports stable scent profiles. In plastics and polymer processing, it acts as a crosslinker and heat stabilizer, participating in curing reactions that improve thermal resistance and structural integrity of polymer matrices.
Tert-Amyl Alcohol is supplied in standard industrial and high-purity grades, with availability conforming to FCC specifications for food-contact applications and REACH registration requirements for EU market compliance. Typical packaging includes drums and IBC containers. Procurement teams should confirm grade suitability against application-specific regulatory requirements prior to ordering.
