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 Anagrelide Impurity 24.
CATO supplies Anagrelide Impurity 24 (CAS 147249-41-0), a pharmacopoeial impurity reference standard (molecular formula C7H4Cl2N2, MW 187.03 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C7H4Cl2N2, Anagrelide Impurity 24 contains a nitrile group, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 187.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Anagrelide Impurity 24 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.
