Lansoprazole Impurity 37 CAS 103312-62-5

Description

Compared with other compounds in its class, the molecular weight of 289.78 g/mol gives Lansoprazole Impurity 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Lansoprazole Impurity 37 (CAS 103312-62-5), a pharmacopoeial impurity reference standard (molecular formula C14H12ClN3S, MW 289.78 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Lansoprazole Impurity 37 (C14H12ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 289.78 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Lansoprazole Impurity 37 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.
