Ethyl 2-((4-chloro-3-methylphenyl)thio)-2-oxoacetate CAS 1443312-32-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-((4-chloro-3-methylphenyl)thio)-2-oxoacetate.

Ethyl 2-((4-chloro-3-methylphenyl)thio)-2-oxoacetate (CAS 1443312-32-0), molecular formula C11H11ClO3S and molecular weight 258.72 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C11H11ClO3S, Ethyl 2-((4-chloro-3-methylphenyl)thio)-2-oxoacetate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.72 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
