Chemical Structure
Description
5-(Furan-2-yl)-3-(4-methoxyphenyl)-4,5-dihydro-1h-pyrazole-1-carbothioamide (CAS 394682-47-4) is a high-purity analytical reference standard with the molecular formula C15H15N3O2S and a molecular weight of 301.36 g/mol.
The molecular framework of 5-(Furan-2-yl)-3-(4-methoxyphenyl)-4,5-dihydro-1h-pyrazole-1-carbothioamide (C15H15N3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
