132794-08-2 4-Chloro-2,5-difluorobenzoyl chloride 4-chloro-2,5-difluorobenzoyl chloride 97% 4-chloro-2,5-difluorobenzoylchloride97% benzoyl chloride, 4-chloro-2,5-difluoro- (9ci) (CAS 132794-08-2) is a high-purity analytical reference standard with the molecular formula C7H2Cl2F2O and a molecular weight of 210.99 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 132794-08-2 4-Chloro-2,5-difluorobenzoyl chloride 4-chloro-2,5-difluorobenzoyl chloride 97% 4-chloro-2,5-difluorobenzoylchloride97% benzoyl chloride, 4-chloro-2,5-difluoro- (9ci) is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 210.99 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.
