Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Reactivity profile: Isoamyl acetate is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. This compound can react violently with oxidizing materials, nitrates, strong alkalis and strong acids. (NTP, 1992) [National Toxicology Program, Institute of Environmental Health Sciences, National Institutes of Health (NTP). 1992. National Toxicology Program Chemical Repository Database. Research Triangle Park, North Carolina]
Reactivity: Thermal decomposition of isoamyl acetate may produce acrid fumes. Contact with strongoxidizing agents, strong acids, and alkaline materials should be avoided (Haarmann & Reimer Corp., 1994). Hazardous decompositionproducts of isoamyl acetate include CO and CO2 (AESAR/Alfa, 1994).

Based on the molecular structure of isopentyl acetate oxidising properties are not expected. The statement on oxidising properties in "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance", subchapter "R.7.1.13.2 Oxidising liquids" (ECHA, 2012) applies: "the substance is incapable of reacting exothermically with combustible materials, for example on the basis of the chemical structure (e.g. organic substances not containing oxygen or halogen atoms and these elements are not chemically bonded to nitrogen or oxygen, or inorganic substances not containing oxygen or halogen atoms)."
Key value for chemical safety assessment
- Oxidising properties:
- no
Additional information
Justification for classification or non-classification
The substance does not appear to have oxidising properties judged by the information from the indicated data sources.
Furthermore, isopentyl acetate was not classified as oxidising in REGULATION (EC) No 1272/2008 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 16 December 2008 (CLP Regulation).
Based the molecular structure of isopentyl acetate oxidising properties are not expected.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
