Chemical Structure
Description
6'-tert-Butyl-1-[(1H-indazol-5-yl)carbonyl]-3',4'-dihydrospiro[piperidine-4,2'-pyrano[3,2-c]pyrazole]-4'-amine (CAS 1353011-96-7), molecular formula C22H28N6O2 and molecular weight 408.50 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 6'-tert-Butyl-1-[(1H-indazol-5-yl)carbonyl]-3',4'-dihydrospiro[piperidine-4,2'-pyrano[3,2-c]pyrazole]-4'-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
