CAS 132684-60-7: fmoc-L-tert-leucine

Description:Fmoc-L-tert-leucine, with the CAS number 132684-60-7, is a protected form of the amino acid leucine, commonly used in peptide synthesis. The "Fmoc" (9-fluorenylmethoxycarbonyl) group serves as a protective moiety that allows for selective deprotection during the synthesis process, facilitating the assembly of peptides without interfering with the amino acid's reactivity. This compound features a tert-butyl side chain, which contributes to its hydrophobic characteristics, making it useful in the synthesis of peptides that require stability and solubility in organic solvents. Fmoc-L-tert-leucine is typically white to off-white in appearance and is soluble in organic solvents such as dimethylformamide (DMF) and dimethyl sulfoxide (DMSO), but less soluble in water. Its stability under standard laboratory conditions makes it a valuable reagent in organic chemistry and biochemistry, particularly in solid-phase peptide synthesis. Additionally, the Fmoc group can be removed under mild basic conditions, allowing for the subsequent coupling of other amino acids to form longer peptide chains.
