Other Information
The CAS number of unspecified crotonic acid is 3724-65-0 and cis-crotonic acid has CAS 503-64-0.The trans isomer is also called just crotonic acid, while the cis isomer is called isocrotonic acid. Commercially (unspecified) crotonic acid consists mainly (or even completely) of the trans isomer. Synonyms of unspecified crotonic acid are: alpha-crotonic acid, beta-methylacrylic acid and 3-methylacrylic acid.In general the substance will be transported as molten liquid.
