Reagents, also known as biochemical reagents or reagents. Reagents are mainly to realize the pure chemicals used in chemical reactions, analytical tests, research experiments, teaching experiments, and chemical formulas. Generally the the reagents are divided into general reagents, high-purity reagents, analytical reagents, instrumental analytical reagents, clinical diagnostic reagents, biochemical reagents, inorganic ion color reagent reagents, etc.

Pharmaceutical Excipients
Pharmaceutical excipients refer to excipients and additives used in the production of drugs and formulating prescriptions; in addition to the active ingredients, they have been reasonably evaluated in terms of safety and are included in pharmaceutical preparations. In addition to excipients, serving as carriers, and improving stability, pharmaceutical excipients also have important functions such as solubilization, solubilization, and slow and controlled release. They are important ingredients that may affect the quality, safety and effectiveness of drugs.
