Chemical Structure
Description
The occurrence of Benzylpenicillin Impurity N1 is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Benzylpenicillin Impurity N1 (CAS 64950-14-7) is a certified pharmaceutical impurity reference standard with the molecular formula C7H14N2O2S and a molecular weight of 190.26 g/mol.
Benzylpenicillin Impurity N1 (C7H14N2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Benzylpenicillin Impurity N1 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
