Chemical Structure

1’-cyclopentyl-6’-oxo-1’,5’,6’,7’-tetrahydrospiro[cyclohexane-1,4’-pyrazolo[3,4-b]pyridine]-5’-carbonitrile CAS 923152-34-5 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.

1’-cyclopentyl-6’-oxo-1’,5’,6’,7’-tetrahydrospiro[cyclohexane-1,4’-pyrazolo[3,4-b]pyridine]-5’-carbonitrile (CAS 923152-34-5), molecular formula C17H22N4O and molecular weight 298.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1’-cyclopentyl-6’-oxo-1’,5’,6’,7’-tetrahydrospiro[cyclohexane-1,4’-pyrazolo[3,4-b]pyridine]-5’-carbonitrile (C17H22N4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
