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.
5-(1-Amino-2-methylpropyl)-1,3,4-thiadiazol-2-amine dihydrochloride (CAS 1243250-16-9), molecular formula C6H12N4SHCl and molecular weight 208.71 g/mol, is a CATO reference standard with documented purity and traceability.
5-(1-Amino-2-methylpropyl)-1,3,4-thiadiazol-2-amine dihydrochloride (C6H12N4SHCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
