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 (3,5-Dichloro-2-hydroxyphenyl)(phenyl)methanone.
(3,5-Dichloro-2-hydroxyphenyl)(phenyl)methanone (CAS 7396-92-1) is a high-purity analytical reference standard with the molecular formula C13H8Cl2O2 and a molecular weight of 267.11 g/mol.
The molecular framework of (3,5-Dichloro-2-hydroxyphenyl)(phenyl)methanone (C13H8Cl2O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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.
