5-(Piperidin-1-ylsulfonyl)-1H-indole-2,3-dione CAS 329905-79-5

Description

The occurrence of 5-(Piperidin-1-ylsulfonyl)-1H-indole-2,3-dione is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-(Piperidin-1-ylsulfonyl)-1H-indole-2,3-dione (CAS 329905-79-5), a certified reference material (molecular formula C13H14N2O4S, MW 294.33 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-(Piperidin-1-ylsulfonyl)-1H-indole-2,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
