Chemical Structure

3-Ethyl-5-hydroxybenzonitrile CAS 1243400-19-2 chemical structure

Description

CATO supplies 3-Ethyl-5-hydroxybenzonitrile (CAS 1243400-19-2), a certified reference material (molecular formula C9H9NO, MW 147.17 g/mol) for analytical method development and quality control.

The molecular framework of 3-Ethyl-5-hydroxybenzonitrile (C9H9NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).

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.
