Chemical Structure
Description
The occurrence of 4-Methyl-1,2,3-thiadiazol-5-amine is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methyl-1,2,3-thiadiazol-5-amine (CAS 6440-01-3), molecular formula C3H5N3S and molecular weight 115.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Methyl-1,2,3-thiadiazol-5-amine (C3H5N3S) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 115.16 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
