Chemical Structure
Description
Owing to bromine substitution, an aromatic ring system, 1-Bromo-8-(bromomethyl)naphthalene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
1-Bromo-8-(bromomethyl)naphthalene (CAS 72758-17-9) is a high-purity analytical reference standard with the molecular formula C11H8Br2 and a molecular weight of 299.99 g/mol.
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-8-(bromomethyl)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.
