Properties Suppliers
Adenosine 5′-Diphosphate Sodium Salt

Adenosine 5'-Diphosphate Sodium Salt can be used as the intermedium in pharmaceutical and chemical industry, and also as a biochemical reagent.

Properties Suppliers
Adenosine Cyclic 3',5'-Monophosphate

Adenosine Cyclic 3',5'-Monophosphate is a second messenger important in many biological processes.It is derived from adenosine triphosphate (ATP) and used for intracellular signal transduction in many different organisms, conveying the cAMP-dependent pathway.It is synthesised from ATP by adenylyl cyclase located on the inner side of the plasma membrane.It is involved in the activation of protein kinases and regulates the effects of adrenaline and glucagon. It also regulates the passage of Ca2+ through ion channels,positive regulation of the lac operon.

Arsenia is mainly for refining of arsenic metal, which is also raw material for melting arsenic alloys and produce semiconductors. It uses as clarifying agent and decolorising agent in glass industry, which improve transparency of glass products.

In farming, arsenic(III) oxide apply as sanitizer and rust remover for insect disease prevention, which is also raw material for insecticidal pesticide containing arsenic.

Arsenic oxide use to produce coating and dyestuff. It is also kind of chemical reagent as standard reagent, reducing agent and absorbent of chlorine.

As2O3 get applications in desulfuration, anticorrosion of wood, antiscale of boiler, ceramic,  enamel, lether preservative and medicine.
