Description of key information

In air: 1 TO 7.5% ; HSDB, original data source: Sax, N.I. and R.J. Lewis, Sr. (eds.). Hawley's Condensed Chemical Dictionary. 11th ed. New York: Van Nostrand Reinhold Co., 1987., p. 650Y

Moderately explosive in the form of vapor when exposed to heat or flame. HSDB orginal source Lewis, R.J. Sr. (ed) Sax's Dangerous Properties of Industrial Materials. 11th Edition. Wiley-Interscience, Wiley & Sons, Inc. Hoboken, NJ. 2004., p. 2114

There are no chemical groups in the molecule of isopentyl acetate which point to explosive properties. Judgement based on "Table R.7.1-28 Chemical groups associated with explosive properties" in "Guidance on information requirements and chemical safety assessment Chapter R.7a: Endpoint specific guidance" (ECHA, May 2008).

Key value for chemical safety assessment

non explosive

Additional information

Justification for classification or non-classification

The substance is regarded and classified as non explosive based on the given data in this data set and the official classification in REGULATION (EC) No 1272/2008 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 16 December 2008 on classification, labelling and packaging of substances and mixtures, amending and repealing Directives 67/548/EEC and 1999/45/EC, and amending Regulation (EC) No 1907/2006 (pages 547 and 1081).

The molecular structure of isopentyl acetate also points to no explosive hazard.
