(R)-2-Amino-3-(7-methyl-1H-indol-3-yl)propanoic acid (CAS 99295-80-4), molecular formula C12H14N2O2 and molecular weight 218.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-2-Amino-3-(7-methyl-1H-indol-3-yl)propanoic acid (C12H14N2O2) is characterized by an amino-acid-derived structure, an amide 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.
