Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.33 g/mol gives 4-(Benzo[d]thiazol-2-ylthio)but-2-yn-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(Benzo[d]thiazol-2-ylthio)but-2-yn-1-ol (CAS 431067-90-2), a certified reference material (molecular formula C11H9NOS2, MW 235.33 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H9NOS2, 4-(Benzo[d]thiazol-2-ylthio)but-2-yn-1-ol contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 235.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
