Chemical Structure
Description
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.
3-Methyl-6,7,8,9-tetrahydro-5h-[1,2,4]triazolo[4,3-d][1,4]diazepine (CAS 1083274-19-4), molecular formula C7H12N4 and molecular weight 152.20 g/mol, is a CATO reference standard with documented purity and traceability.
3-Methyl-6,7,8,9-tetrahydro-5h-[1,2,4]triazolo[4,3-d][1,4]diazepine (C7H12N4) contains a nitrile group, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
