Description
CATO manufactures 8'-Bromo-3',4'-dihydro-2'H-spiro[cyclopropane-1,1'-naphthalene] 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.
8'-Bromo-3',4'-dihydro-2'H-spiro[cyclopropane-1,1'-naphthalene] (CAS 1781879-96-6), molecular formula C12H13Br and molecular weight 237.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, an aromatic ring system, 8'-Bromo-3',4'-dihydro-2'H-spiro[cyclopropane-1,1'-naphthalene] is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 237.14 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.
