Lidocaine Impurity 71 CAS CATO-C4X-167971 chemical structure

Description

CATO manufactures Lidocaine Impurity 71 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.

CATO supplies Lidocaine Impurity 71 (CAS CATO-C4X-167971), a pharmacopoeial impurity reference standard (molecular formula C14H23N3O, MW 249.35 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Lidocaine Impurity 71 (C14H23N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 249.35 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
