Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-3-methoxy-3-methylbutanoic acid (CAS 75974-47-9) is a high-purity analytical reference standard with the molecular formula C6H11BrO3 and a molecular weight of 211.05 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 2-Bromo-3-methoxy-3-methylbutanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.05 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.
As a certified reference material (CRM), 2-Bromo-3-methoxy-3-methylbutanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
