[Product use]: D-Phenylglycine is an optically active compound, which is a penicillin-based deep-processing product.
Ampicillin, Oxyperazine, Apocillin, and Cephalosporin
Important intermediates such as pyridine and cefaclor. The higher its optical purity, the more toxic and side effects of the synthesized antibiotic
The smaller, the higher the physiological activity, the stronger the antibacterial ability.
