D-Cysteine Chemical Properties,Usage,Production

Chemical Properties

White crystalline powder

Uses

D-Cysteine has been used in the functionalization of QDs for applications in photocatalysis.
It can also be used in the synthesis of:

cysteine-based chiral carbon dots (CDs)
D-luciferin and aminoluciferin analogs

Definition

ChEBI: An optically active form of cysteine having D-configuration.

Purification Methods

Purify it by recrystallisation from H2O (free from metal ions) and dry it in a vacuum. It is soluble in H2O, EtOH, Me2CO, EtOAc, AcOH, *C6H6 and CS2. Acidic solutions can be stored under N2 for a few days without deterioration. [For synthesis and spectra see Greenstein & Winitz Chemistry of the Amino Acids (J. Wiley) Vol 3 p1879 1961, Beilstein 4 III 1618, 4 IV 3144.]
