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-Methyl-1,3,4-thiadiazole-2-carbonitrile.
5-Methyl-1,3,4-thiadiazole-2-carbonitrile (CAS 518015-09-3) is a high-purity analytical reference standard with the molecular formula C4H3N3S and a molecular weight of 125.15 g/mol.
Structurally, 5-Methyl-1,3,4-thiadiazole-2-carbonitrile (C4H3N3S) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 125.15 g/mol, it falls into the low-molecular-weight range. 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.
