2-(4-Ethylphenyl)-2-hydroxyacetic acid CAS 10408-52-3

Description

Compared with other compounds in its class, the molecular weight of 180.20 g/mol gives 2-(4-Ethylphenyl)-2-hydroxyacetic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(4-Ethylphenyl)-2-hydroxyacetic acid (CAS 10408-52-3), molecular formula C10H12O3 and molecular weight 180.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(4-Ethylphenyl)-2-hydroxyacetic acid (C10H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 180.20 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
