Kuphatikizika kwachilengedwe kwa 4-hydroxyphenylacetic acid. Organic synthesis intermediates amagwiritsidwa ntchito popanga β - receptor blocker atenolol ndi chogwiritsidwa ntchito cha Pueraria lobata daidzein -4,7-dihydroxyflavone; 4-Hydroxyphenylacetic acid itha kugwiritsidwanso ntchito ngati mankhwala apakati. Acylation reaction reagents kwa phenolic mankhwala ndi amine mankhwala.
Nthawi zambiri ankanyamula 25kg/ng'oma, komanso akhoza kuchita makonda phukusi.
