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-1-chloro-2-(propan-2-yl)benzene.
CATO supplies 4-Bromo-1-chloro-2-(propan-2-yl)benzene (CAS 90350-28-0), a certified reference material (molecular formula C9H10BrCl, MW 233.53 g/mol) for analytical method development and quality control.
Structurally, 4-Bromo-1-chloro-2-(propan-2-yl)benzene (C9H10BrCl) contains chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 233.53 g/mol, it falls into the medium-molecular-weight range. 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.
