138-43-2 Usage

General Description

Sodium [[4-(aminosulphonyl)phenyl]amino]methanesulphonate is a chemical compound commonly known as Sodium Dapsone. It is a synthetic sulfone medication used primarily as an antibacterial and anti-inflammatory agent. Sodium Dapsone is commonly used in combination with other antibiotics to treat leprosy and dermatitis herpetiformis. It works by inhibiting the growth of bacteria and reducing inflammation in the body. However, it can cause serious side effects, including a potentially fatal condition called methemoglobinemia, and should be used with caution and under the supervision of a healthcare professional.

Check Digit Verification of cas no

The CAS Registry Mumber 138-43-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138-43:
(5*1)+(4*3)+(3*8)+(2*4)+(1*3)=52
52 % 10 = 2
So 138-43-2 is a valid CAS Registry Number.

Method for synthesizing sodium (4-sulfonamidoaniline) methanesulfonate

-

Paragraph 0047-0066, (2019/10/01)

The invention discloses a method for synthesizing sodium (4-sulfonamidoaniline) methanesulfonate. The method comprises the following steps: S1, adding an aqueous solution of sodium hydrogen sulfite into a formaldehyde solution, controlling a temperature, regulating a first pH value to be weakly alkaline, and introducing gases to expel formaldehyde; adding activated carbon, performing filtering toobtain a first filtrate, and regulating a second pH value of the first filtrate to be acidic so as to obtain a sodium hydroxymethanesulphonate solution; and S2, heating sulfanilamide and water to obtain an aqueous solution, and dropping the sodium hydroxymethanesulphonate solution into the aqueous solution in a certain time so as to react; adding activated carbon to filter so as to obtain a secondfiltrate, adding ethanol into the second filtrate for performing stirring, and performing after-treatment to obtain the sodium (4-sulfonamidoaniline) methanesulfonate. Due to high solubility in water, the sodium (4-sulfonamidoaniline) methanesulfonate can be applied to infection prevention of injection, drip and operations, and is used for infection caused by streptococcus, gonococcus and the like. The synthetic method is high in yield and meets industrial production requirements.
