Isovaleraldehyde can react with acetic acid anhydride to get acetic acid-(3-methyl-but-1-enyl ester).

When you are dealing with this chemical, you should be very careful. This chemical may cause inflammation to the skin or other mucous membranes. It may catch fire in contact with air, only need brief contact with an ignition source and have a very low flash point or evolve highly flammable gases in contact with water. And it is irritating to eyes, respiratory system and skin. Therefore, you should wear suitable protective clothing, gloves and eye/face protection. You must keep container tightly closed and keep away from sources of ignition. In case of contacting with eyes, you should rinse immediately with plenty of water and seek medical advice.

You can still convert the following datas into molecular structure:
(1) SMILES: O=CCC(C)C
(2) InChI: InChI=1S/C5H10O/c1-5(2)3-4-6/h4-5H,3H2,1-2H3
(3) InChIKey: YGHRJJRRZDOVPD-UHFFFAOYSA-N
