LabChem® Sodium Phenate Solution

LabChem® SODIUM PHENATE SOLUTION is a ready-to-use alkaline phenol reagent, a key component of the phenol-hypochlorite colorimetric method for ammonia determination. When combined with sodium hypochlorite and a nitroprusside catalyst, phenate reacts with ammonia to form an intensely blue indophenol color proportional to ammonia concentration. Providing the reagent pre-mixed removes the need for in-house preparation.

It is widely used as a color-developing reagent in the phenol-hypochlorite method for ammonia determination in water and wastewater testing. Its consistent, ready-mixed formulation supports reproducible results across testing sessions. This reagent should be handled, stored, and used according to established laboratory safety procedures and the manufacturer's instructions.
