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.
2-(Chloromethyl)-N,N,5-trimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (CAS 1280654-95-6) is a high-purity analytical reference standard with the molecular formula C9H12ClN5 and a molecular weight of 225.68 g/mol.
2-(Chloromethyl)-N,N,5-trimethyl-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (C9H12ClN5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
