Chemical Structure

Agomelatine Impurity 23 CAS 178676-65-8 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 Agomelatine Impurity 23.

Agomelatine Impurity 23 (CAS 178676-65-8) is a certified pharmaceutical impurity reference standard with the molecular formula C13H13NO and a molecular weight of 199.25 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Agomelatine Impurity 23 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 199.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Agomelatine Impurity 23 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
