The naturally occuring isomer is the L-form which has been found in apples and many other fruits and plants. Selective a-amino protecting reagent for amino acid derivatives. Versatile synthon for the preparation of chiral compounds including κ-opioid receptor agonists, 1a,25-dihydroxyvitamin D3 analogue, and phoslactomycin B. Used to selectively protect the a-amino group of amino acids.It is the starting material for the preparation of chiral compounds.Melting Point: 101-103°CHeavy Metals:≤10mg/Kg (as Pb)Arsenic (As2O2):≤2mg/KgChloride (Cl-):≤0.004%Sulfate (SO42-):≤0.02%Fumaric Acid:≤0.5% Maleic Acid:≤0.05%Optical Rotation:[a]D20 = -1.6 to -2.6°Transmission:State of solution: To pass testResidue on Ignition:0.10%Storage:Store at RT.
