Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lacidipine Impurity 29 (E-Isomer).
CATO supplies Lacidipine Impurity 29 (E-Isomer) (CAS 180515-27-9), a pharmacopoeial impurity reference standard (molecular formula C20H26O4, MW 330.42 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C20H26O4, Lacidipine Impurity 29 (E-Isomer) contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Lacidipine Impurity 29 (E-Isomer) 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.
