261762-43-0 3-chloranyl-2,6-bis(fluoranyl)benzoyl chloride 3-chloro-2,6-difluorobenzoyl chloride A818251 CAS 261762-43-0

Description

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.

261762-43-0 3-chloranyl-2,6-bis(fluoranyl)benzoyl chloride 3-chloro-2,6-difluorobenzoyl chloride A818251 (CAS 261762-43-0), molecular formula C7H2Cl2F2O and molecular weight 210.99 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 261762-43-0 3-chloranyl-2,6-bis(fluoranyl)benzoyl chloride 3-chloro-2,6-difluorobenzoyl chloride A818251 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
