Description
2-Carboxy-5-nitrobenzenesulfonic acid potassium salt, also known as Potassium 2-Carboxy-5-nitrobenzenesulfonate, is an organic compound with the chemical formula C7H4KN2O7S. It is a potassium salt derived from 2-carboxy-5-nitrobenzenesulfonic acid and is characterized by its acidic properties and reactivity in various chemical reactions.
Uses
Used in Pharmaceutical Industry:
2-Carboxy-5-nitrobenzenesulfonic acid potassium salt is used as an intermediate in the synthesis of N,N-Dimethyl-2-aminosulfonyl-4-formamidobenzamide (D896870) for the preparation of the sulfonylurea herbicide Foramsulfuron (F685003). This application is significant in the development of agricultural chemicals that help control weed growth, thereby increasing crop yield and efficiency.
Additionally, this compound may also find use in other chemical synthesis processes where its specific functional groups and reactivity are required for the production of various pharmaceuticals, agrochemicals, or other specialty chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 5344-48-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,4 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5344-48:
(6*5)+(5*3)+(4*4)+(3*4)+(2*4)+(1*8)=89
89 % 10 = 9
So 5344-48-9 is a valid CAS Registry Number.
