Fmoc-D-Cys(tBu)-OH

Description:
Fmoc-D-Cys(tBu)-OH, with the CAS number 131766-22-8, is a protected form of the amino acid cysteine, specifically the D-enantiomer. The "Fmoc" (9-fluorenylmethoxycarbonyl) group serves as a protective group for the amino functionality, facilitating its use in peptide synthesis by preventing unwanted reactions. The "Cys" indicates the presence of a cysteine residue, which contains a thiol (-SH) group that can form disulfide bonds, crucial for protein structure and function. The "(tBu)" denotes a tert-butyl group attached to the thiol, providing steric hindrance and enhancing stability during synthesis. This compound is typically utilized in solid-phase peptide synthesis and other applications where selective protection of functional groups is necessary. Its characteristics include solubility in organic solvents, stability under standard laboratory conditions, and reactivity that allows for subsequent coupling reactions. Overall, Fmoc-D-Cys(tBu)-OH is an important building block in the field of peptide chemistry and biochemistry.
