Chemical Structure

Netilmicin EP Impurity B CAS 67666-41-5 chemical structure

Description

CATO supplies Netilmicin EP Impurity B (CAS 67666-41-5), a pharmacopoeial impurity reference standard (molecular formula C15H31N3O6, MW 349.42 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Netilmicin EP Impurity B (C15H31N3O6) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 349.42 g/mol, it falls into the moderately-high-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 Netilmicin EP Impurity B 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.
