Chemical Structure
Description
The occurrence of 2-Bromo-2-methylpropanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Bromo-2-methylpropanoic acid (CAS 2052-01-9), a certified reference material (molecular formula C4H7BrO2, MW 167.00 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 2-Bromo-2-methylpropanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.00 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Bromo-2-methylpropanoic acid 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.
