Chemical Structure

6,8-Dibromo-2H-chromene-3-carbaldehyde CAS 885271-27-2 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 6,8-Dibromo-2H-chromene-3-carbaldehyde.

6,8-Dibromo-2H-chromene-3-carbaldehyde (CAS 885271-27-2) is a high-purity analytical reference standard with the molecular formula C10H6Br2O2 and a molecular weight of 317.96 g/mol.

6,8-Dibromo-2H-chromene-3-carbaldehyde (C10H6Br2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
