2-(3-Iodo-1H-indazol-5-yl)spiro[cyclopropane-1,3'-indolin]-2'-one CAS 1799434-54-0

Description

2-(3-Iodo-1H-indazol-5-yl)spiro[cyclopropane-1,3'-indolin]-2'-one (CAS 1799434-54-0) is a high-purity analytical reference standard with the molecular formula C17H12IN3O and a molecular weight of 401.20 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution, 2-(3-Iodo-1H-indazol-5-yl)spiro[cyclopropane-1,3'-indolin]-2'-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 401.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
