Hydrolyzed starch syrups

(8029-43-4)
Corn Syrup is a corn sweetener that is a viscous liquid containing maltose, dextrin, dextrose, and other polysaccharides. it is obtained from the incomplete hydrolysis of cornstarch. it is classified accord- ing to the degree of conversion which is expressed as the dextrose equivalent (de), which is the measure of sweetness of the corn syrup as compared to that of a sucrose syrup. generally, the greater the degree of conversion, the sweeter the syrup. corn syrup is used as a replacement fo

Heptafluorobutyric anhydride

(336-59-4)
As a GC derivatizing agent, Heptafluorobutyric anhydride is used to prepare volatile derivatives of amino acids and other biologically active compounds. Heptafluorobutyric anhydride (HFAA)  is frequently used as an acylating agent for the derivatization of primary and secondary amines (Walle and Ehrsson, 1971). Commercially available Heptafluorobutyric anhydride may afford low yields of the derivative due to the presence of Heptafluorobutyric acid (Moodie et al., 1985). This contaminant may be

Bulk drug intermediates are the drugs used as raw materials for the production of bulk drugs, or they can refer to a material produced during synthesis of an API that must undergo further molecular change or processing before it becomes an API.

More Information

Intermediates are unavoidable products of chemical reactions and are widely used in pharmaceuticals, materials, chemicals, and other industries.

In the pharmaceutical industry, an active pharmaceutical ingredient (API) is a product of a synthesis process that has been completed and is used in the manufacture of bulk drugs and intermediates are some chemical raw materials or chemical products used in the synthesis process of APIs.

The application industries of pharmaceutical intermediates mainly include antibiotics, anticancer drugs, cardiovascular drugs, neurological drugs, hormone drugs, and immunosuppression.

Functions of intermediates

Intermediates serve a variety of responsibilities in the drug production process.

● They can serve as a link between the API and the finished medicine. The drug production process can be broken down into multiple steps using intermediates, each requiring a different chemical.

● They can modify reaction conditions and synthesis pathways, increasing drug synthesis efficiency and yields.

● They can be employed to modify the purification, crystallization, and solid characteristics of medicines.
