In the pharmaceutical field, it is an intermediate for antibiotics and can be used to synthesize various acylimidazoles, pyranoamide, etc. It is also an important intermediate for the synthesis of pyranoamide. Under amine functionalization conditions, it can be used as a silanization reagent to protect hydroxyl groups for the preparation of multiple derivatives of compounds containing both hydroxyl and amino groups. Silanized sugar can be used in the presence of a small amount of water. It is an ideal choice when sugar needs to be analyzed as a syrup agent. Most steroid hydroxyl groups can be derived without obstruction or with severe obstruction.
In the field of organic synthesis: It is an extremely powerful silanizing agent. As a powerful silanizing reagent, it is particularly targeted at alcohols. It is a commonly used silanizing reagent in organic chemistry and can be used for the protection of organic synthetic groups.
