HYDRATE OF BETA-LACTAM ANTIBIOTIC SUBSTANCE

摘要

The crystalline dihydrate and trihydrate forms of the antibiotic 7 beta -[2 min -(R)-2 min -phenyl-2 min -aminoacetamido]-3-chloro-3-(1-carbadethiacep hem)-4-carboxylic acid ("LY163892") are described. These hydrates are antibiotics in their own right, and are valuable intermediates to the corresponding monohydrate form of LY163892.
