Chemical Structure
Description
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.
4-(1-(Ethylthio)-3-methyl-2H-isoindol-2-yl)butanoic acid (CAS 95710-65-9), molecular formula C15H19NO2S and molecular weight 277.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(1-(Ethylthio)-3-methyl-2H-isoindol-2-yl)butanoic acid (C15H19NO2S) 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.
