Application

Citric acid monohydrate may be used:
• To prepare citric acid solution employed in the acetone method of 68Ga pre-purification and radiolabeling technique.
• To prepare Tris-citrate buffer employed for the electrophoresis of bacterial enzymes.
• To improve the release of diltiazem hydrochloride from melt extruded matrix tablets.

General description

Citric acid monohydrate(CAM) is an organic acid. It can be produced by crystallization from mother liquor of citric acid solution at 20-25°C during citric acid synthesis. Its molar enthalpy of solution in water has been reported to be ΔsolHm (298.15K, m = 0.0203molkg-1) = (29061±123)Jmol-1. An investigation of its crystal growth kinetics indicates that growth is linearly dependent on size.
