DL-Threonine is the racemic form of threonine, an alpha-amino acid (2-amino-3-hydroxybutanoic acid) consisting of butanoic acid substituted by an amino group at position 2 and a hydroxy group at position 3. It is used in pharmaceuticals and nutritional formulations, and as a starting material for optical resolution to obtain the individual L- and D-threonine enantiomers. This crystalline solid has a CAS number of 80-68-2, a molecular formula of C4H9NO3, and a molecular weight of 119.12 g/mol. It requires no special storage conditions and carries no signal word for hazard classification. Molekula supplies DL-Threonine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
