Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl (S)-2-hydroxy-3-(3-methoxyphenyl)propanoate.
Ethyl (S)-2-hydroxy-3-(3-methoxyphenyl)propanoate (CAS 1187926-95-9) is a high-purity analytical reference standard with the molecular formula C12H16O4 and a molecular weight of 224.25 g/mol.
The molecular framework of Ethyl (S)-2-hydroxy-3-(3-methoxyphenyl)propanoate (C12H16O4) 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.
