Chemical Structure
Description
The occurrence of 2,6-dichlorobenzenediazonium tetrafluoroborate is closely related to a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,6-dichlorobenzenediazonium tetrafluoroborate (CAS 387-41-7), molecular formula C6H3Cl2N2BF4 and molecular weight 260.81 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine/chlorine substitution, 2,6-dichlorobenzenediazonium tetrafluoroborate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.81 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
