4-Hydroxyphenylacetic Acid | 156-38-7
Ukucaciswa Komkhiqizo
I-white acicular crystalline solid ngaphansi kwezinga lokushisa elivamile nokucindezela.
Inoncibilika kahle emanzini, kodwa incibilika kalula kuzincibilikisi ezivamile zemvelo, okuhlanganisa i-ethyl acetate, i-Dimethyl sulfoxide, njll.
I-P-hydroxy Phenylacetic acid ingeyamakhemikhali e-phenol. Ihlanganiswe neqembu le-carboxyl esakhiweni salo, into ibonisa i-acidity eqinile.
