Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 175.18 g/mol gives 2-(4-Cyano-2-methylphenyl)acetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(4-Cyano-2-methylphenyl)acetic acid (CAS 34841-56-0), molecular formula C10H9NO2 and molecular weight 175.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-Cyano-2-methylphenyl)acetic acid (C10H9NO2) is characterized by an amino-acid-derived structure, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
