Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 183.27 g/mol gives N-cyclopentyl-5-methyl-1,3,4-thiadiazol-2-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-cyclopentyl-5-methyl-1,3,4-thiadiazol-2-amine (CAS 299422-24-5), a certified reference material (molecular formula C8H13N3S, MW 183.27 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, N-cyclopentyl-5-methyl-1,3,4-thiadiazol-2-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.27 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).
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.
