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.
CATO supplies tert-Butyl 5-(benzyloxy)-3-methyl-1H-pyrazolo[3,4-b]pyridine-1-carboxylate (CAS 864775-97-3), a certified reference material (molecular formula C19H21N3O3, MW 339.39 g/mol) for analytical method development and quality control.
tert-Butyl 5-(benzyloxy)-3-methyl-1H-pyrazolo[3,4-b]pyridine-1-carboxylate (C19H21N3O3) 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).
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.
