Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 239.33 g/mol gives Ethyl 3-((2-amino-5-methylphenyl)thio)propanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 3-((2-amino-5-methylphenyl)thio)propanoate (CAS 1531675-87-2) is a high-purity analytical reference standard with the molecular formula C12H17NO2S and a molecular weight of 239.33 g/mol.
The molecular framework of Ethyl 3-((2-amino-5-methylphenyl)thio)propanoate (C12H17NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
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.
