1-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-4-(thiophen-2-ylsulfonyl)piperazine CAS 1396851-91-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 354.49 g/mol gives 1-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-4-(thiophen-2-ylsulfonyl)piperazine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-4-(thiophen-2-ylsulfonyl)piperazine (CAS 1396851-91-4), molecular formula C15H22N4O2S2 and molecular weight 354.49 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-(2-(3,5-Dimethyl-1H-pyrazol-1-yl)ethyl)-4-(thiophen-2-ylsulfonyl)piperazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.49 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.

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.
