Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 342.69 g/mol gives Sertraline EP Impurity A HCl (1S,4R-Isomer) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sertraline EP Impurity A HCl (1S,4R-Isomer) (CAS 79896-31-4), a pharmacopoeial impurity reference standard (molecular formula C17H17Cl2NHCl, MW 342.69 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C17H17Cl2NHCl, Sertraline EP Impurity A HCl (1S,4R-Isomer) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 342.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Sertraline EP Impurity A HCl (1S,4R-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.
