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 2-Fluoro-4-methyl-3-(trifluoromethyl)benzoyl chloride.
2-Fluoro-4-methyl-3-(trifluoromethyl)benzoyl chloride (CAS 1824271-04-6) is a high-purity analytical reference standard with the molecular formula C9H5ClF4O and a molecular weight of 240.58 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2-Fluoro-4-methyl-3-(trifluoromethyl)benzoyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2-Fluoro-4-methyl-3-(trifluoromethyl)benzoyl chloride 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.
