Chemical Structure

3-Oxo-2-(o-tolyl)butanenitrile CAS 75205-42-4 chemical structure

Description

CATO supplies 3-Oxo-2-(o-tolyl)butanenitrile (CAS 75205-42-4), a certified reference material (molecular formula C11H11NO, MW 173.21 g/mol) for analytical method development and quality control.

The molecular framework of 3-Oxo-2-(o-tolyl)butanenitrile (C11H11NO) 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 its high hydrophobicity (logP), 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.

CATO manufactures 3-Oxo-2-(o-tolyl)butanenitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
