Chemical Structure

Lacosamide Impurity 43 CAS 69805-82-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Lacosamide Impurity 43.

CATO supplies Lacosamide Impurity 43 (CAS 69805-82-9), a pharmacopoeial impurity reference standard (molecular formula C12H17NO2, MW 207.27 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Lacosamide Impurity 43 (C12H17NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Lacosamide Impurity 43 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.
