[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.
[reaction suitability]

reaction type: solution phase peptide synthesis
[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.
