I-DL-Pyroglutamic acid (CAS # 149-87-1) isingeniso
I-DL pyroglutamic acid iyi-amino acid, eyaziwa nangokuthi i-DL-2-aminoglutaric acid. I-DL pyroglutamic acid iyimpushana ecwebezelayo engenambala encibilika emanzini ne-ethanol.

Ngokuvamile kunezindlela ezimbili zokukhiqiza i-DL pyroglutamic acid: i-chemical synthesis kanye ne-microbial fermentation. Ukuhlanganiswa kwamakhemikhali kutholakala ngokusabela izinhlanganisela ezifanele, kuyilapho ukuvutshelwa kwe-microbial kusebenzisa ama-microorganisms athile ukuze kugaywe futhi kuhlanganiswe i-amino acid.

Imininingwane yokuphepha ye-DL pyroglutamic acid: Ithathwa njengenhlanganisela ephephile engenabo ubuthi obubonakalayo. Njengekhemikhali, kufanele igcinwe futhi isetshenziswe ngaphansi kwezimo ezifanele, ukugwema ukuthintana nama-oxidants aqinile. Ngaphambi kokusebenzisa i-DL pyroglutamic acid, kufanele isingathwe ngokuya ngezinqubo ezifanele zokusebenza kanye nezinyathelo zokuzivikela.

Okwedlule: I-2-BROMO-6-FLUOROPYRIDINE (CAS# 144100-07-2)

Olandelayo: I-Dodecyltributylphosphonium Bromide (CAS# 15294-63-0)
