Anhydrous calcium hydrogen phosphate is a white, free-flowing inorganic excipient widely used in solid oral dosage forms.

It functions as a diluent and dry binder for direct compression tablets and capsules, offering excellent flowability, low hygroscopicity, and good tablet hardness.

In food and nutraceuticals, it is used as a bioavailable source of calcium and phosphorus to support bone and mineral health.

Its chemical stability, low reactivity, and excellent processing performance make it a preferred filler in modern formulation design.
