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.
tert-Butyl 7-(benzyloxy)-5-iodo-[1,2,4]triazolo[1,5-a]pyridine-8-carboxylate (CAS 1262132-97-7) is a high-purity analytical reference standard with the molecular formula C18H18IN3O3 and a molecular weight of 451.26 g/mol.
Structurally, tert-Butyl 7-(benzyloxy)-5-iodo-[1,2,4]triazolo[1,5-a]pyridine-8-carboxylate (C18H18IN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 451.26 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.
