L-2,4-Diaminobutyric acid dihydrochloride

Yellowish powder. Soluble in water. Unnatural amino acid derivative. Pharmacological tool and potential chiral building block used as an internal standard for amino acid analysis. Suitable reagent used for the differentiation of beta-N-methylamino-L-alanine from the diamino acids by using HPLC-FD, UHPLC-UV, UHPLC-MS, and triple quadrupole tandem mass spectrometry (UHPLC-MS/MS). Used in the quantification of neurotoxin beta-N-methylamino-L-alanine (BMAA) in seafood. It has been found to inhibit GABA transaminase (ABAT), producing elevated levels of GABA and to have an antitumor activity.
