Chemical Structure
Description
7-chloro-3-propyl-[1,2,4]triazolo[4,3-c]pyrimidine (CAS 1152578-03-4), molecular formula C8H17ClN4 and molecular weight 204.70 g/mol, is a CATO reference standard with documented purity and traceability.
7-chloro-3-propyl-[1,2,4]triazolo[4,3-c]pyrimidine (C8H17ClN4) contains 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
