Chemical Structure
Description
CATO supplies 4-chloro-1-methyl-1H-pyrazolo[3,4-b]pyridine (CAS 1268520-92-8), a certified reference material (molecular formula C7H14ClN3, MW 175.66 g/mol) for analytical method development and quality control.
4-chloro-1-methyl-1H-pyrazolo[3,4-b]pyridine (C7H14ClN3) contains a nitrile group, chlorine 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.
