Chemical Structure
Description
CATO manufactures 3-Bromo-2-methylpropene 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.
3-Bromo-2-methylpropene (CAS 1458-98-6), molecular formula C4H7Br and molecular weight 135.00 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, 3-Bromo-2-methylpropene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 135.00 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.
