N-Nitroso Piperacillin impurity 103 CAS CATO-C4X-1732103

Description

The occurrence of N-Nitroso Piperacillin impurity 103 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies N-Nitroso Piperacillin impurity 103 (CAS CATO-C4X-1732103), a pharmacopoeial impurity reference standard (molecular formula C6H9N3O3, MW 171.15 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, N-Nitroso Piperacillin impurity 103 (C6H9N3O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 171.15 g/mol, it falls into the medium-molecular-weight range. 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 N-Nitroso Piperacillin impurity 103 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.
