Description
CATO manufactures (5-Bromonaphthalen-2-yl)methanol 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.
(5-Bromonaphthalen-2-yl)methanol (CAS 128104-53-0) is a high-purity analytical reference standard with the molecular formula C11H9BrO and a molecular weight of 237.09 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, (5-Bromonaphthalen-2-yl)methanol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 237.09 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.
