Chemical Structure
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-(2-bromoethyl)oxetane (CAS 2167840-77-7), molecular formula C5H9BrO and molecular weight 165.03 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, bromine substitution, 2-(2-bromoethyl)oxetane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 165.03 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.
CATO manufactures 2-(2-bromoethyl)oxetane 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.
