Chemical Structure
Description
CATO supplies tert-Butyl 3-iodo-1,5,6,7-tetrahydropyrazolo[4,3-b]pyridine-4-carboxylate (CAS 1251014-79-5), a certified reference material (molecular formula C11H16IN3O2, MW 349.17 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution, tert-Butyl 3-iodo-1,5,6,7-tetrahydropyrazolo[4,3-b]pyridine-4-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
