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.
CATO supplies 2-Phenyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine hydrochloride (CAS 300552-48-1), a certified reference material (molecular formula C13H13N3HCl, MW 247.73 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H13N3HCl, 2-Phenyl-5,6,7,8-tetrahydropyrido[4,3-d]pyrimidine hydrochloride 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 247.73 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
