Chemical Structure
Description
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.
4-chloro-3-iodo-1H-pyrazolo[3,4-b]pyridine (CAS 949558-30-9) is a high-purity analytical reference standard with the molecular formula C6H11ClIN3 and a molecular weight of 287.53 g/mol.
4-chloro-3-iodo-1H-pyrazolo[3,4-b]pyridine (C6H11ClIN3) contains a nitrile group, chlorine/iodine 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.
