3-Bromo-4-chloro-5-fluorobenzoyl chloride CAS 1807036-13-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Bromo-4-chloro-5-fluorobenzoyl chloride.

CATO supplies 3-Bromo-4-chloro-5-fluorobenzoyl chloride (CAS 1807036-13-0), a certified reference material (molecular formula C7H2BrCl2FO, MW 271.90 g/mol) for analytical method development and quality control.

Structurally, 3-Bromo-4-chloro-5-fluorobenzoyl chloride (C7H2BrCl2FO) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine 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 271.90 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
