Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2,3-Dichloro-4-(ethylsulfonyl)phenyl)ethan-1-one.

1-(2,3-Dichloro-4-(ethylsulfonyl)phenyl)ethan-1-one (CAS 338982-46-0), molecular formula C10H10Cl2O3S and molecular weight 281.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(2,3-Dichloro-4-(ethylsulfonyl)phenyl)ethan-1-one (C10H10Cl2O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 281.16 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures 1-(2,3-Dichloro-4-(ethylsulfonyl)phenyl)ethan-1-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
