Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-Methyl-5-[(2-phenoxyethyl)sulfanyl]-1,3,4-thiadiazole (CAS 339011-37-9), a certified reference material (molecular formula C11H12N2OS2, MW 252.36 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-Methyl-5-[(2-phenoxyethyl)sulfanyl]-1,3,4-thiadiazole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 252.36 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).
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.
