GENERAL DESCRIPTION & APPLICATIONS |
||
|
Phenylacetic acid is a white crystals with a disagreeable odor; boiling point
262 C; soluble in alcohol and ether. It serves as an ingredient in perfume to
provide honey-like odor. It is found as a moiety in some alkaloids and plant
hormones. It is formed as catabolite of phenylalanine. Substituted phenylacetic
acid molecule at alpha position and phenylacetate esters can serve as a drug
with a wide variety of effects including anticholinergic, muscarinic antagonist,
antidote to cholinesterase inhibitors or toxins, cycloplegic and mydriatic.
Phenylacetic acid is used to prepare a nonsteroidal antiinflammatory drug like
diclofenac. It is used the manufacture of penicillin. Mandelic Acid,
phenylglycollic acid, can be produced from phenylchloracetic acid.
p-Hydroxyphenylacetic acid is used as an intermediate for pharmaceuticals (especially for dextromethorphan) and agrochemicals including plant growth regulator and herbicide. |
