(E)-Methyl 5-bromopent-2-enoate CAS 67810-57-5 chemical structure

Description

CATO manufactures (E)-Methyl 5-bromopent-2-enoate 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.

(E)-Methyl 5-bromopent-2-enoate (CAS 67810-57-5) is a high-purity analytical reference standard with the molecular formula C6H9BrO2 and a molecular weight of 193.04 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, (E)-Methyl 5-bromopent-2-enoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.04 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.
