Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-bromo-4-butoxy-5-ethoxybenzaldehyde (CAS 881601-64-5) is a high-purity analytical reference standard with the molecular formula C13H17BrO3 and a molecular weight of 301.18 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 3-bromo-4-butoxy-5-ethoxybenzaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 301.18 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).
CATO manufactures 3-bromo-4-butoxy-5-ethoxybenzaldehyde 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.
