Chemical Structure
Description
The occurrence of Ethyl 1-methyl-4-((4-methylbenzyl)amino)-1H-pyrazolo[3,4-b]pyridine-5-carboxylate 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.
Ethyl 1-methyl-4-((4-methylbenzyl)amino)-1H-pyrazolo[3,4-b]pyridine-5-carboxylate (CAS 1221715-29-2) is a high-purity analytical reference standard with the molecular formula C18H20N4O2 and a molecular weight of 324.38 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Ethyl 1-methyl-4-((4-methylbenzyl)amino)-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 324.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
