Chemical Structure
Description
2-Amino-4-(p-tolyl)butanoic acid (C11H15NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-Amino-4-(p-tolyl)butanoic acid (CAS 225233-71-6), molecular formula C11H15NO2 and molecular weight 193.24 g/mol, is a CATO reference standard with documented purity and traceability.
