Description
CATO supplies 1-Bromo-5-(4-chlorophenyl)-2-methylbenzene (CAS 1033760-75-6), a certified reference material (molecular formula C13H10BrCl, MW 281.58 g/mol) for analytical method development and quality control.
Owing to chlorine/bromine substitution, an aromatic ring system, 1-Bromo-5-(4-chlorophenyl)-2-methylbenzene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 281.58 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.
CATO manufactures 1-Bromo-5-(4-chlorophenyl)-2-methylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
