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 5-Bromo-2-(chloromethyl)-1,3-dimethylbenzene.
5-Bromo-2-(chloromethyl)-1,3-dimethylbenzene (CAS 205035-07-0), molecular formula C9H10BrCl and molecular weight 233.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine/bromine substitution, an aromatic ring system, 5-Bromo-2-(chloromethyl)-1,3-dimethylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 233.53 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
