Chemical Structure

2-Bromoisobutyryl Bromide CAS 20769-85-1 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 2-Bromoisobutyryl Bromide (CAS 20769-85-1), a certified reference material (molecular formula C4H6Br2O, MW 229.90 g/mol) for analytical method development and quality control.

The molecular framework of 2-Bromoisobutyryl Bromide (C4H6Br2O) is characterized by a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
