2-(3,4-Dimethylphenyl)-3-methylbutanoic acid CAS 55776-82-4

Description

The occurrence of 2-(3,4-Dimethylphenyl)-3-methylbutanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(3,4-Dimethylphenyl)-3-methylbutanoic acid (CAS 55776-82-4), molecular formula C13H18O2 and molecular weight 206.28 g/mol, is a CATO reference standard with documented purity and traceability.

2-(3,4-Dimethylphenyl)-3-methylbutanoic acid (C13H18O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.

As a certified reference material (CRM), 2-(3,4-Dimethylphenyl)-3-methylbutanoic 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.
