Chemical Structure
Description
The molecular framework of 2,3-Dimethyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine (C8H13N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 2,3-Dimethyl-4,5,6,7-tetrahydropyrazolo[1,5-a]pyrimidine (CAS 4879-22-5), a certified reference material (molecular formula C8H13N3, MW 151.21 g/mol) for analytical method development and quality control.
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.
