Di-tert-butyl dicarbonate CAS NO.24424-99-5

advantage

Safety: To synthesize a compound that is the same as a natural polypeptide, it is necessary to connect various optically active amino acids into a peptide chain of a certain length in a certain order. When it is necessary to combine the carboxyl group of one amino acid with the amino group of another amino acid, it is necessary to prevent the interaction between the molecules of the same amino acid. Therefore, some amino or carboxyl groups must be protected during synthesis, so that the reaction can be carried out in the required way, This product is an amino acid protector with good performance. Compared with traditional amino acid protectors such as benzyl chloroformate and chloroformic-P-fluorenoic acid, it has the following advantages:

1. Batch production, large output, and relative cost saving.

2. It has no strong irritating taste and no toxic effect on human body, but it can cause skin allergy after direct contact with skin, so it can be washed with water.

3. When this product is used to synthesize polypeptide, the removal condition of the protective gene is mild, and the separation and purification of the product with good reaction is easier than using other types of amino acid protectors.

4. Flammable, but not flammable and explosive.
