Fmoc-Asn(Trt)-OH Chemical Properties,Uses,Production

Description

Fmoc-Asn(Trt)-OH prevents the possibility of the amide side chain from undergoing dehydration side reactions during activation, especially with carbodiimide reagents. Fmoc-Asn(Trt)-OH dissolves readily in all standard peptide synthesis reagents, while Fmoc-Asn-OH is only somewhat soluble in NMP or DMF. The trityl group is removed with TFA. This reaction is usually complete within 1 hour at room temperature, but is slower when the Asn(Trt) residue in at the N-terminal of the peptide. In these cases, the deprotection reaction should be extended to 2 hours.

Uses

Fmoc-Asn(Trt)-OH, is an amino acid derivative used in chemical synthesis and peptide chemistry.

Preparation

Synthesis of Fmoc-Asn(Trt)-OH:
Step 1: Crystallization to form N'-Trityl-L-asparagine crystals.
Step 2: Centrifugation to extract N'-Trityl-L-asparagine crystals.
Step 3: Washing to remove residual starting materials in the synthesis.
Step 4: Extraction to obtain N-Acetyl-L-asparagine.
Step 5: Centrifugation to extract N'-Trityl-L-asparagine.
Step 6: Drying to obtain the final product.
This synthesis method effectively removes residual synthetic materials such as trifluoroacetic acid, maleic anhydride, and epichlorohydrin, which are similar in chemical properties to N-Acetyl-L-asparagine, from the product during the production process. The purification method is simple and the product obtained has high purity.
