Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-7-methylnaphthalene.
1-Bromo-7-methylnaphthalene (CAS 7511-27-5), molecular formula C11H9Br and molecular weight 221.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, an aromatic ring system, 1-Bromo-7-methylnaphthalene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 221.09 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.
CATO manufactures 1-Bromo-7-methylnaphthalene 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.
