Description

Product Detail

Fmoc-l-aspartate beta-tert-butyl is a FMOC-protected 4-tert-butyl L-aspartate, a protective form of L-aspartate, which is a white to pale yellow crystalline powder. Beta-tert-butyl FMOC-L-aspartate is a chemical synthesis intermediate of natural acidic amino acid L-aspartate, which is an important intermediate of organic synthesis. Due to the existence of ester group and amino group in the molecule, it is easy to polymerize and has poor stability, so it is not suitable for long-term storage (refer to relevant literature)
