Chemical Structure

Levocarnitine impurity 33 CAS 931426-06-1 chemical structure

Description

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 supplies Levocarnitine impurity 33 (CAS 931426-06-1), a pharmacopoeial impurity reference standard (molecular formula C6H10O4, MW 146.14 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Levocarnitine impurity 33 (C6H10O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

CATO manufactures Levocarnitine impurity 33 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.
