(4-Chloro-2-fluorobenzyl)(4-chloro-3-fluorophenyl)sulfane CAS 1443353-03-4

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-2-fluorobenzyl)(4-chloro-3-fluorophenyl)sulfane.

(4-Chloro-2-fluorobenzyl)(4-chloro-3-fluorophenyl)sulfane (CAS 1443353-03-4), molecular formula C13H8Cl2F2S and molecular weight 305.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system, (4-Chloro-2-fluorobenzyl)(4-chloro-3-fluorophenyl)sulfane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 (4-Chloro-2-fluorobenzyl)(4-chloro-3-fluorophenyl)sulfane 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.
