Ethyl 1-[2-(methylsulfonyl)-4-nitrophenyl]-piperidine-4-carboxalate CAS 951625-05-1

Description

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.

CATO supplies Ethyl 1-[2-(methylsulfonyl)-4-nitrophenyl]-piperidine-4-carboxalate (CAS 951625-05-1), a certified reference material (molecular formula C15H20N2O6S, MW 356.39 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Ethyl 1-[2-(methylsulfonyl)-4-nitrophenyl]-piperidine-4-carboxalate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.39 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.

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.
