What are the physical and chemical properties of N-[(Benzyloxy)carbonyl]-3-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}-D-alanine (CAS: 185968-90-5)?

N-[(Benzyloxy)carbonyl]-3-{[(9H-fluoren-9-ylmethoxy)carbonyl]amino}-D-alanine is a white crystalline solid with a molecular weight of approximately 821.47 g/mol. It is poorly soluble in water but soluble in organic solvents. Its reactivity is moderate, particularly toward nucleophilic substitution and condensation reactions. It is stable under normal conditions but should be stored in a cool, dry place away from light and moisture to prevent degradation.
