Description

Compared with other compounds in its class, the molecular weight of 397.27 g/mol gives 5-{[(2,6-dichlorophenyl)sulfanyl]methyl}-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-{[(2,6-dichlorophenyl)sulfanyl]methyl}-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole (CAS 478031-74-2), molecular formula C14H9Cl2F3N2S2 and molecular weight 397.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, 5-{[(2,6-dichlorophenyl)sulfanyl]methyl}-1-methyl-3-(trifluoromethyl)-1H-thieno[2,3-c]pyrazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.27 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.
