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 Tadalafil Impurity 34.
CATO supplies Tadalafil Impurity 34 (CAS 2058231-15-3), a pharmacopoeial impurity reference standard (molecular formula C22H21N3O5HCl, MW 443.88 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C22H21N3O5HCl, Tadalafil Impurity 34 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 443.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 Tadalafil Impurity 34 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.
