Methyl 3-((4-(2,5-dimethylphenyl)piperazin-1-yl)sulfonyl)thiophene-2-carboxylate CAS 895262-86-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 3-((4-(2,5-dimethylphenyl)piperazin-1-yl)sulfonyl)thiophene-2-carboxylate.

Methyl 3-((4-(2,5-dimethylphenyl)piperazin-1-yl)sulfonyl)thiophene-2-carboxylate (CAS 895262-86-9) is a high-purity analytical reference standard with the molecular formula C18H22N2O4S2 and a molecular weight of 394.51 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 3-((4-(2,5-dimethylphenyl)piperazin-1-yl)sulfonyl)thiophene-2-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 394.51 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
