Structurally, tert-butyl 2-(tert-butoxycarbonylamino)-3-iodo-4,6,7,8-tetrahydropyrazolo[1,5-a][1,4]diazepine-5-carboxylate (C17H27IN4O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 478.33 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
tert-butyl 2-(tert-butoxycarbonylamino)-3-iodo-4,6,7,8-tetrahydropyrazolo[1,5-a][1,4]diazepine-5-carboxylate (CAS 2791275-56-2) is a high-purity analytical reference standard with the molecular formula C17H27IN4O4 and a molecular weight of 478.33 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
