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-Chlorophenyl)(2,5-dimethylthiophen-3-yl)methanone.
CATO supplies (4-Chlorophenyl)(2,5-dimethylthiophen-3-yl)methanone (CAS 57248-23-4), a certified reference material (molecular formula C13H11ClOS, MW 250.74 g/mol) for analytical method development and quality control.
The molecular framework of (4-Chlorophenyl)(2,5-dimethylthiophen-3-yl)methanone (C13H11ClOS) is characterized by sulfur-containing functionality, 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.
