Chemical Structure
Description
The occurrence of 6-Bromo-2-chloro-1,8-naphthyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Bromo-2-chloro-1,8-naphthyridine (CAS 902837-40-5), molecular formula C8H4BrClN2 and molecular weight 243.49 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution, 6-Bromo-2-chloro-1,8-naphthyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 243.49 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.
