CAPSO Na, also known as 3- (cyclohexylamine) -2-hydroxy-1-propanesulfonic acid monosodium salt, is a biological buffer. The following is an introduction to the basic biological information about CAPSO Na: Appearance: CAPSO Na is a white to grayish white powder, odorless, and slightly salty in taste. Characteristics: It is easily soluble in water, slightly soluble in ethanol, and insoluble in acetone. Usage: CAPSO Na is mainly used as a biological buffer and can be used in molecular biology and biochemistry experiments to regulate pH and maintain the pH of solutions. Advantages: The advantage of CAPSO Na is its strong buffering ability, which can stabilize the pH value in the solution. In addition, it also has good solubility and stability, which can ensure the accuracy and reliability of experimental results.
