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 4-Chloro-N-(4,6-diphenylpyrimidin-2-yl)benzamide.
4-Chloro-N-(4,6-diphenylpyrimidin-2-yl)benzamide (CAS 820961-59-9), molecular formula C23H16ClN3O and molecular weight 385.85 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Chloro-N-(4,6-diphenylpyrimidin-2-yl)benzamide (C23H16ClN3O) 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
