I-Protocatechuic acid CAS 99-50-3 I-Protocatechuic acid (PCA) yi-3,4-dihydroxybenzoic acid. I-asidi ye-phenolic elula, eyi-precursor ye-synthesis yezinye iimolekyuli eziyinkimbinkimbi, ezifana ne-anthocyanin 3-ochemicalbook- β- D-glucoside kunye ne-vanillin. Ifumaneka kwimifuno etyiwayo, iziqhamo, amandongomane, irayisi emdaka, iipecans, iti, iintyatyambo zehibiscus kunye namanye amayeza esintu aseTshayina.
I-Believe Chemical yi-China ehamba phambiliProtocatechuic acid CAS 99-50-3umenzi, umthengisi kunye nomthumeli ngaphandle. Ukubambelela ekusukeleni umgangatho ogqibeleleyo weemveliso, ukuze wethuProtocatechuic acid CAS 99-50-3ziye zaneliswa ngabathengi abaninzi. Shandong Kholwa
Silungile kwiingenelo zeemveliso zemichiza kwintsimi. Iimveliso zethu zithunyelwa eYurophu, eUnited States, Japan, South Korea, Southeast Asia nakwamanye amazwe kunye nemimandla. Ngenzululwazi kunye netekhnoloji njengesikhokelo, ukunyaniseka njengesiseko, umgangatho njengobomi, kunye nokuthembela kwingqikelelo yeshishini lokusungula izinto ezintsha kunye nophuhliso, sinethemba elinyanisekileyo lokuseka utshintshiselwano kunye nentsebenziswano ebanzi kunye nabathengi basekhaya nabangaphandle ukudala impumelelo!
