Physical and chemical properties
Those separated from water are white needle-like crystals. The relative molecular mass is 152.15. The melting point is 149-151°C. can sublimate. Insoluble in cold water, soluble in hot water, ether, ethanol and ethyl acetate. When p-hydroxyphenylacetic acid encounters ferric chloride, it becomes purple-green precipitate. Used as pharmaceutical raw materials for the preparation of cephalosporin antibiotics, antipyretic analgesics, etc.; pesticide raw materials for the preparation of pyrethroid insecticides; fluorescent reagents for the determination of oxidase; intermediates in organic synthesis.
