4'-Sulfamoylphthalanic acid, also known as 4'-(Aminosulfonyl)phthalic acid, is an organic compound with the chemical formula C8H7NO5S. It is a white crystalline solid that is soluble in water and slightly soluble in ethanol. 4'-SULFAMOYLPHTHALANILIC ACID is a key intermediate in the synthesis of various pharmaceuticals, particularly nonsteroidal anti-inflammatory drugs (NSAIDs) and sulfonamide antibiotics. It is used in the production of drugs like sulindac, a NSAID, and sulfasalazine, an anti-inflammatory and immunosuppressive drug. The compound is synthesized through the reaction of phthalic anhydride with chlorosulfonic acid, followed by the addition of ammonia. Due to its reactivity and potential to form harmful byproducts, it is important to handle 4'-sulfamoylphthalanic acid with care, adhering to proper safety protocols.

6955-49-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6955-49-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,5 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6955-49:
(6*6)+(5*9)+(4*5)+(3*5)+(2*4)+(1*9)=133
133 % 10 = 3
So 6955-49-3 is a valid CAS Registry Number.

Spectrophotometric and Titrimetric Determination of Carboxylic Acid Anhydrides

Verma, Krishna K.,Tyagi, Pramila

, p. 2157 - 2160 (2007/10/02)

Two redox methods are described for the determination of carboxylic acid anhydrides involving reaction with either an excess of 4-aminophenol or a measured but excessive amount of sulfanilamide and photometric titration of N-acyl-4-aminophenol with 2-iodylbenzoate by measuring the absorbance of orange-red product at 444 nm or the residual amount of sulfanilamide is determined by titration with chloramine-T in the presence of acidified potassium bromide using methyl red as visual indicator.Mixtures of certain anhydrides have also been analyzed by the 2-iodylbenzoate method.The methods are rapid, precise, and accurate.No correlation is needed if carboxylic and mineral acids are also present.Carboxylic acid chlorides also react quantitatively.
