Chemical Structure
Description
The occurrence of Ethyl (R)-2-(4-hydroxyphenoxy)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 (R)-2-(4-hydroxyphenoxy)propanoate (CAS 71301-98-9), molecular formula C11H14O4 and molecular weight 210.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl (R)-2-(4-hydroxyphenoxy)propanoate (C11H14O4) 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 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.
CATO manufactures Ethyl (R)-2-(4-hydroxyphenoxy)propanoate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
