Delving into the specific chemical makeup and properties of a compound is crucial for its effective application in research and manufacturing. N-[Fluorenylmethoxycarbonyl]-S-[[(2-phenylacetyl)amino]methyl]-L-cysteine, with CAS number 159680-21-4, is a sophisticated organic molecule whose detailed profile, offered by NINGBO INNO PHARMCHEM CO.,LTD., is vital for scientists and engineers in the pharmaceutical industry.

The molecular formula of this compound is C27H26N2O5S, and its molecular weight is approximately 490.57100. This precise composition dictates its reactivity and behavior in synthetic processes. At its core, it's a modified amino acid derivative, specifically L-cysteine. The amino group is protected by the Fmoc (9-fluorenylmethoxycarbonyl) moiety, a large, sterically hindered group that shields the amine during synthetic steps and can be readily removed using mild bases. This is a standard strategy in peptide synthesis, allowing for controlled chain elongation.

The sulfur atom of the cysteine side chain is functionalized with an S-[[(2-phenylacetyl)amino]methyl] group. This means a methyl group is attached to the sulfur, which in turn is linked to an amino group that is acylated with a 2-phenylacetyl residue. This specific functionalization adds complexity and potential points of interaction within larger molecular structures, making it particularly useful for creating unique peptide sequences or for the synthesis of complex APIs where such a sulfur-containing, modified amino acid is required.

In terms of physical characteristics, N-[Fluorenylmethoxycarbonyl]-S-[[(2-phenylacetyl)amino]methyl]-L-cysteine typically appears as a white powder. This form is convenient for handling, weighing, and dissolution in common organic solvents used in synthesis. Its density is noted as 1.315±0.06 g/cm³, providing a measure of its compactness. While specific data on melting points and flash points are often not as readily available for highly specialized intermediates, its predicted boiling point is high, around 782.7±60.0 °C, suggesting considerable thermal stability. For any manufacturer or researcher looking to buy this compound, understanding these properties is key to optimizing storage and reaction conditions.

Proper storage is crucial for maintaining the compound's high purity (≥98%). It should be kept in a tightly closed container, ideally in a cool, dry, and well-ventilated place, such as a secure dispenser. This prevents degradation from moisture, light, or air, which could compromise its effectiveness in sensitive synthesis pathways.
