N-(5-Methyl-1,3,4-thiadiazol-2-yl)formamide CAS 53567-06-9

Description

Compared with other compounds in its class, the molecular weight of 143.17 g/mol gives N-(5-Methyl-1,3,4-thiadiazol-2-yl)formamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(5-Methyl-1,3,4-thiadiazol-2-yl)formamide (CAS 53567-06-9) is a high-purity analytical reference standard with the molecular formula C4H5N3OS and a molecular weight of 143.17 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, N-(5-Methyl-1,3,4-thiadiazol-2-yl)formamide is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
