Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-NITRO-1,3,4-THIADIAZOL-2-AMINE.
5-NITRO-1,3,4-THIADIAZOL-2-AMINE (CAS 26907-62-0) is a high-purity analytical reference standard with the molecular formula C2H2N4O2S and a molecular weight of 146.13 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 5-NITRO-1,3,4-THIADIAZOL-2-AMINE is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.13 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.
