Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-3-chloro-1H-pyrazolo[3,4-c]pyridine (CAS 929617-31-2), molecular formula C6H3BrClN3 and molecular weight 232.47 g/mol, is a CATO reference standard with documented purity and traceability.
5-Bromo-3-chloro-1H-pyrazolo[3,4-c]pyridine (C6H3BrClN3) contains a nitrile group, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
