DL-Pipecolinic acid Usage And Synthesis
UsesPipecolic acid is involved in synaptic transmission in the central nervous system.
DefinitionChEBI: Pipecolic acid is a piperidinemonocarboxylic acid in which the carboxy group is located at position C-2. It is a conjugate acid of a pipecolate.
Purification MethodsIt crystallises from water. The (±)-picrate has m 158-159o (from EtOH or C6H6). [Beilstein 22 H 7, 22 III/IV 97, 22/1 V 220.] The R(+)-enantiomer [1723-00-8] has m 277o(dec) and [] D 20 +27o (c 4, H2O), and the S(-)-enantiomer [3105-95-1] has m 277o(dec) and [] D 20 -26o (c 4, H2O).[cf p 603, Beilstein 22 III/IV 96, 22/1 V 220.]
