Chemical Structure

3-(1-Methyl-1H-pyrazol-3-yl)benzonitrile CAS 207909-05-5 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.

3-(1-Methyl-1H-pyrazol-3-yl)benzonitrile (CAS 207909-05-5), molecular formula C11H9N3 and molecular weight 183.21 g/mol, is a CATO reference standard with documented purity and traceability.

3-(1-Methyl-1H-pyrazol-3-yl)benzonitrile (C11H9N3) 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.
