Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2K-322S 3-{5,6-dichloro-1-[(4-chlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one 338774-07-5.

2K-322S 3-{5,6-dichloro-1-[(4-chlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one 338774-07-5 (CAS 338774-07-5) is a high-purity analytical reference standard with the molecular formula C19H12Cl3N3O and a molecular weight of 404.68 g/mol.

The molecular framework of 2K-322S 3-{5,6-dichloro-1-[(4-chlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one 338774-07-5 (C19H12Cl3N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2K-322S 3-{5,6-dichloro-1-[(4-chlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one 338774-07-5 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.
