Comparative evaluation of determination of beta-lactam intermediates.
The Schiff's base formation between 6-aminopenicillanic acid, 7-aminodesacetoxycephalosporanic acid and 7-aminocephalosporanic acid and p-dimethylaminobenzaldehyde (PDAB) was investigated. The factors that affect the reaction such as concentration of PDAB, time and pH were studied and optimised for estimation of these intermediates.
