232-656-0

Proprietà chimiche

Modulo
Lyophilized powder, 480 kDa
Solubilità
It is slightly soluble in water.

Applicazioni

It is suitable for the determination of urea. It is also used as chemical reagents, pharmaceutical intermediates. It is an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.

Note

Min 45 units/mg dry wt. One unit oxidizes one micromole of NADH per minute at 25°C and pH 7.6. The hydrolysis of urea is measured by coupling ammonia production to a glutamate dehydrogenase reaction.
