4626-94-2 Usage
General Description
Ethylsulphamic acid is a chemical compound that is composed of ethyl and sulphamic acid groups. It is a white crystalline solid that is soluble in water and non-volatile. It is used as a corrosion inhibitor, flame retardant, and in the production of pharmaceuticals and pesticides. Ethylsulphamic acid is also used as a descaling agent in the cleaning of industrial equipment and as a catalyst in organic synthesis. It is stable under normal conditions but can decompose at high temperatures, releasing toxic fumes of sulfur oxides. Overall, ethylsulphamic acid has various industrial applications due to its corrosion inhibiting and flame retardant properties.
Check Digit Verification of cas no
The CAS Registry Mumber 4626-94-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,2 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4626-94:
(6*4)+(5*6)+(4*2)+(3*6)+(2*9)+(1*4)=102
102 % 10 = 2
So 4626-94-2 is a valid CAS Registry Number.

, (2008/06/13)
This invention relates to compounds characterized by the presence of N-methyl, or substituted methyl, phosphonic acid and N-hydroxy-propylenesulfonic acid groups. These compounds contain at least one or more of each group and are bonded to the same or different amino groups. They are derived by reacting an amine with both (1) an epihalohydrin-bisulfite addition product and (2) with a carbonyl compound, such as formaldehyde, and phosphorous acid or its equivalent. They have a wide variety of uses, for example as scale and corrosion inhibitors, iron oxide removers, chelating agents, etc.
