Chemical Structure
Description
1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-N,N-dimethyl-1H-1,2,3,4-tetrazol-5-amine (C9H8ClF3N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/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.
1-[3-Chloro-5-(trifluoromethyl)pyridin-2-yl]-N,N-dimethyl-1H-1,2,3,4-tetrazol-5-amine (CAS 338751-32-9) is a high-purity analytical reference standard with the molecular formula C9H8ClF3N6 and a molecular weight of 292.65 g/mol.
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.
