Chemical Structure
Description
The occurrence of Citalopram Impurity 49 Chloride (and enantiomer) is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Citalopram Impurity 49 Chloride (and enantiomer) (CAS CATO-C4X-110990), a pharmacopoeial impurity reference standard (molecular formula C21H23ClFN2OCl, MW 409.33 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C21H23ClFN2OCl, Citalopram Impurity 49 Chloride (and enantiomer) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 409.33 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 Citalopram Impurity 49 Chloride (and enantiomer) 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.
