23. Compliant The technical requirements for determining the moisture content in drugs using the Karl Fischer method in pharmacopoeia.

The Karl Fischer method was proposed by Karl Fischer in 1935. It uses I2, SO2, pyridine, and anhydrous CH3OH (with a water content of less than 0.05%) to prepare reagents, and measures the water equivalent of the reagents. After the reagents react with the water in the sample, the water content in the sample is calculated by calculating the reagent consumption. The standardization organization has set this method as the standard for measuring trace water. We Also define this method as Standard method for determining trace moisture content.
