Description

The occurrence of 1-Cyclopentyl-3-ethyl-6-(4-methoxybenzyl)-5,6-dihydro-1H-pyrazolo[3,4-c]pyridin-7(4H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Cyclopentyl-3-ethyl-6-(4-methoxybenzyl)-5,6-dihydro-1H-pyrazolo[3,4-c]pyridin-7(4H)-one (CAS 303752-11-6), a certified reference material (molecular formula C21H27N3O2, MW 353.46 g/mol) for analytical method development and quality control.

Structurally, 1-Cyclopentyl-3-ethyl-6-(4-methoxybenzyl)-5,6-dihydro-1H-pyrazolo[3,4-c]pyridin-7(4H)-one (C21H27N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 353.46 g/mol, it falls into the moderately-high-molecular-weight range. 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.
