Chemical Structure
Description
1-Bromo-4-ethoxynaphthalene (CAS 20900-22-5) is a high-purity analytical reference standard with the molecular formula C12H11BrO and a molecular weight of 251.12 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 1-Bromo-4-ethoxynaphthalene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 251.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1-Bromo-4-ethoxynaphthalene 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.
