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 2-(5-Bromo-2-chlorophenyl)-3-methylpyrazolo[1,5-a]pyridine.
CATO supplies 2-(5-Bromo-2-chlorophenyl)-3-methylpyrazolo[1,5-a]pyridine (CAS 2304668-96-8), a certified reference material (molecular formula C14H10BrClN2, MW 321.60 g/mol) for analytical method development and quality control.
Structurally, 2-(5-Bromo-2-chlorophenyl)-3-methylpyrazolo[1,5-a]pyridine (C14H10BrClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 321.60 g/mol, it falls into the moderately-high-molecular-weight range. 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.
