Ethyl 4-((2,4-dichlorobenzyl)amino)-1-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate CAS 1221715-33-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-((2,4-dichlorobenzyl)amino)-1-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate.

Ethyl 4-((2,4-dichlorobenzyl)amino)-1-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate (CAS 1221715-33-8), molecular formula C17H16Cl2N4O2 and molecular weight 379.24 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, chlorine substitution, Ethyl 4-((2,4-dichlorobenzyl)amino)-1-methyl-1H-pyrazolo[3,4-b]pyridine-5-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 379.24 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).

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.
