Based on its molecular formula C14H14ClN7, 3-(4-Chlorophenyl)-7-(piperazin-1-yl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 315.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
3-(4-Chlorophenyl)-7-(piperazin-1-yl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine (CAS 941868-01-5), molecular formula C14H14ClN7 and molecular weight 315.76 g/mol, is a CATO reference standard with documented purity and traceability.
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.
