The reagent grade, which is the highest quality chemical, is suitable for all purposes and is used for carrying out scientific experiments on living organisms.

The laboratory grade chemicals can be used for all non-biological activities. However, it is unfit to be packed and sold for consumption purposes.

The third is the technical grade, which is mainly used for industrial and manufacturing purposes. Also useful in laboratories, when high levels of accuracy are required.
