Ethyl 3-(3-(tert-butyl)-4-hydroxy-5-methylphenyl)propanoate CAS 40200-35-9

Description

The occurrence of Ethyl 3-(3-(tert-butyl)-4-hydroxy-5-methylphenyl)propanoate 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.

Ethyl 3-(3-(tert-butyl)-4-hydroxy-5-methylphenyl)propanoate (CAS 40200-35-9), molecular formula C16H24O3 and molecular weight 264.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 3-(3-(tert-butyl)-4-hydroxy-5-methylphenyl)propanoate (C16H24O3) 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).

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.
