1-Cyclopentyl-3-methyl-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid CAS 934063-00-0

Description

The occurrence of 1-Cyclopentyl-3-methyl-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid 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.

1-Cyclopentyl-3-methyl-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (CAS 934063-00-0), molecular formula C19H19N3O2 and molecular weight 321.37 g/mol, is a CATO reference standard with documented purity and traceability.

1-Cyclopentyl-3-methyl-6-phenyl-1H-pyrazolo[3,4-b]pyridine-4-carboxylic acid (C19H19N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

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.
