Chemical Structure

cis-Tetrahydro-1H-thieno[3,4-d]imidazol-2(3H)-one 5,5-dioxide CAS 40226-95-7 chemical structure

Description

The occurrence of cis-Tetrahydro-1H-thieno[3,4-d]imidazol-2(3H)-one 5,5-dioxide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

cis-Tetrahydro-1H-thieno[3,4-d]imidazol-2(3H)-one 5,5-dioxide (CAS 40226-95-7) is a high-purity analytical reference standard with the molecular formula C5H8N2O3S and a molecular weight of 176.19 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, cis-Tetrahydro-1H-thieno[3,4-d]imidazol-2(3H)-one 5,5-dioxide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.19 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.

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.
