S-2-Aminononanoic acid is a non-proteinogenic, straight-chain amino acid derivative featuring a nine-carbon aliphatic backbone with an amino group at the 2-position and a carboxyl group, classified as a secondary (α) amino acid with a chiral center at C2 indicated by the "S" stereochemical descriptor. The molecule bears a free primary amino functionality and a free carboxylic acid functionality that can exist as zwitterionic forms under appropriate pH conditions, with the long hydrophobic side chain providing a nonpolar, alkyl character that differs from standard proteinogenic amino acid side-chain lengths. In research and synthesis, it is used as a defined building block for preparing modified peptides and peptidomimetics, for structure-property studies of hydrophobic chain effects, and as a substrate or reference material in analytical method development involving amino acid separation and derivatization.
