| introduction | isobutyl chloroformate (Isobutyl chloroformate,IBCF), with C5H9ClO2 molecular formula, is an important chemical raw material, commonly used in organic synthesis and drug synthesis, and is one of the important condensers for the synthesis of peptide compounds. it is a colorless pungent odor liquid and soluble in chloroform. During the preparation of 1.1 new drug Y101, it was found that the quality of the condensing agent had a great influence on the reaction of peptide compounds. In order to make the chemical reaction using the condensing agent proceed smoothly and obtain the reaction product with stable quality, it is necessary to control the quality of the reagents used in the synthesis. |
| application | isobutyl chloroformate is an important chemical raw material, commonly used in organic synthesis and drug synthesis, and is one of the important condensing agents for the synthesis of peptide compounds. it is a colorless pungent liquid and soluble in chloroform. |
| use | for organic synthesis |
