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 4-Bromo-2-chloro-3-methylbenzaldehyde.
CATO supplies 4-Bromo-2-chloro-3-methylbenzaldehyde (CAS 2010198-18-0), a certified reference material (molecular formula C8H6BrClO, MW 233.49 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, 4-Bromo-2-chloro-3-methylbenzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.49 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.
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.
