Chemical Structure

3,6-Dibromocinnolin-4-ol CAS 2172875-07-7 chemical structure

Description

3,6-Dibromocinnolin-4-ol (CAS 2172875-07-7) is a high-purity analytical reference standard with the molecular formula C8H4Br2N2O and a molecular weight of 303.94 g/mol.

3,6-Dibromocinnolin-4-ol (C8H4Br2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
