(5Z)-5-{[2-(1H-pyrazol-1-yl)phenyl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one CAS 956232-89-6

Description

(5Z)-5-{[2-(1H-pyrazol-1-yl)phenyl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one (CAS 956232-89-6) is a high-purity analytical reference standard with the molecular formula C13H9N3OS2 and a molecular weight of 287.36 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, (5Z)-5-{[2-(1H-pyrazol-1-yl)phenyl]methylidene}-2-sulfanylidene-1,3-thiazolidin-4-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
