Chemical Structure

Oxcarbazepine EP Impurity G CAS 15882-79-8 chemical structure

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Oxcarbazepine EP Impurity G is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 251.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Oxcarbazepine EP Impurity G (CAS 15882-79-8) is a certified pharmaceutical impurity reference standard with the molecular formula C17H17NO and a molecular weight of 251.32 g/mol.

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 Oxcarbazepine EP Impurity G 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.
