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 Dipyridamole Impurity 9.
CATO supplies Dipyridamole Impurity 9 (CAS 1449029-14-4), a pharmacopoeial impurity reference standard (molecular formula C11H10Cl3N5, MW 318.59 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, Dipyridamole Impurity 9 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Dipyridamole Impurity 9 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.
