Chemical Structure

2-(2,6-Diethylphenyl)acetic acid CAS 100256-33-5 chemical structure

Description

The molecular framework of 2-(2,6-Diethylphenyl)acetic acid (C12H16O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

2-(2,6-Diethylphenyl)acetic acid (CAS 100256-33-5) is a high-purity analytical reference standard with the molecular formula C12H16O2 and a molecular weight of 192.25 g/mol.

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.

As a certified reference material (CRM), 2-(2,6-Diethylphenyl)acetic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
