Chemical Structure
Description
CATO manufactures 1-Bromo-2-ethoxyethene 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.
CATO supplies 1-Bromo-2-ethoxyethene (CAS 18519-95-4), a certified reference material (molecular formula C4H7BrO, MW 151.00 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, bromine substitution, 1-Bromo-2-ethoxyethene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 151.00 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.
