Chemical Structure
Description
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.
1-((4-Amino-2-methylpyrimidin-5-yl)methyl)-4-methylpyridin-1-ium chloride hydrochloride (CAS 24328-74-3) is a high-purity analytical reference standard with the molecular formula C12H15N4HClCl and a molecular weight of 287.19 g/mol.
1-((4-Amino-2-methylpyrimidin-5-yl)methyl)-4-methylpyridin-1-ium chloride hydrochloride (C12H15N4HClCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
