Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Bisphosphonates Impurity 1.
CATO supplies Bisphosphonates Impurity 1 (CAS 41003-10-5), a pharmacopoeial impurity reference standard (molecular formula C2H9NO7P2, MW 221.04 g/mol) used for the identification and quantification of trace impurities in APIs.
Bisphosphonates Impurity 1 (C2H9NO7P2) contains an amide group, a phosphate ester group, a carboxylic acid 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 Bisphosphonates Impurity 1 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.
