Chemical Structure

(R)-2,2-Dimethyl-1-(3-methyl-4-(5-nitropyridin-2-yl)piperazin-1-yl)propan-1-one CAS 1956437-90-3 chemical structure

Description

(R)-2,2-Dimethyl-1-(3-methyl-4-(5-nitropyridin-2-yl)piperazin-1-yl)propan-1-one (C15H22N4O3) 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.

(R)-2,2-Dimethyl-1-(3-methyl-4-(5-nitropyridin-2-yl)piperazin-1-yl)propan-1-one (CAS 1956437-90-3), molecular formula C15H22N4O3 and molecular weight 306.36 g/mol, is a CATO reference standard with documented purity and traceability.

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.
