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.
CATO supplies Pyridine, 2-ethenyl-, polymer with 1,3-butadiene and ethenylbenzene (CAS 25053-48-9), a certified reference material (molecular formula C7H7NC8H8C4H6, MW 263.38 g/mol) for analytical method development and quality control.
Pyridine, 2-ethenyl-, polymer with 1,3-butadiene and ethenylbenzene (C7H7NC8H8C4H6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
