Description
CATO supplies 7-Bromo-1-chloronaphthalene (CAS 90947-99-2), a certified reference material (molecular formula C10H6BrCl, MW 241.51 g/mol) for analytical method development and quality control.
Owing to chlorine/bromine substitution, an aromatic ring system, 7-Bromo-1-chloronaphthalene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 241.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 7-Bromo-1-chloronaphthalene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
