Chemical Structure
Description
Tert-Butyl 3-(Hydroxymethyl)-1-Methyl-6,7-Dihydro-1H-Pyrazolo[4,3-C]Pyridine-5(4H)-Carboxylate (C13H21N3O3) contains a nitrogen-containing heterocyclic scaffold, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Tert-Butyl 3-(Hydroxymethyl)-1-Methyl-6,7-Dihydro-1H-Pyrazolo[4,3-C]Pyridine-5(4H)-Carboxylate (CAS 1330765-07-5) is a high-purity analytical reference standard with the molecular formula C13H21N3O3 and a molecular weight of 267.32 g/mol.
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.
