N-Fmoc-L-valine, 98%

Description

CAS: 68858-20-8 | C20H21NO4 | 339.39 g/mol

It is potentially useful for proteomics studies and solid phase peptide synthesis techniques. Fmoc-valine (in addition to the other amino acids) is commonly used to synthesize 4-thiazolidinones (e.g. (E)-5-(4-Ethylbenzylidene)-2-thioxothiazolidin-4-one [E925745]) and 4-metathiazanones as well.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
It is potentially useful for proteomics studies and solid phase peptide synthesis techniques. Fmoc-valine (in addition to the other amino acids) is commonly used to synthesize 4-thiazolidinones (e.g. (E)-5-(4-Ethylbenzylidene)-2-thioxothiazolidin-4-one [E925745]) and 4-metathiazanones as well.

Solubility
Solubility in methanol gives very faint turbidity.

Notes
Store away from oxidizing agents. Keep the container tightly closed and place it in a cool, dry and well ventilated condition.
