SulfoMax RR

SulfoMax RR is an all-purpose catalyst used in the oxidation of sulfur dioxide to sulfur trioxide for the manufacture of sulfuric acid, be it from sulfur burning plants or metallurgical off-gas based plants or spent acid regeneration units. Its unique formulation in combination with a ‘Ribbed’ ring form provides better overall conversion. Its physical integrity benefits the user in terms of reduced screening losses year on year thereby offering increased life while maintaining activity.

Sulfoaildenafil

Sulfoaildenafil is a synthetic chemical compound that is a structural analog of sildenafil. It was first reported in 2005, and it is not approved by any health regulation agency. Like sildenafil, sulfoaildenafil is a phosphodiesterase type 5 inhibitor.

Sulfonamide

Sulfonamide is a sulfonyl group connected to an amine group. Sulfonamide is also the basis of several groups of drugs. Sulfonamide drugs were the first antibiotics to be used systemically, and paved the way for the antibiotic revolution in medicine. The first sulfonamide, trade-named Prontosil, was a prodrug.Sulfonamides are prepared by the reaction of a sulfonyl chloride with ammonia or an amine.

Sulfonic Acid

Sulfonic Acid refers to a member of the class of organosulfur compounds with the general formula R−S(=O)2−OH, where R is an organic alkyl or aryl group and the S(=O)2−OH group a sulfonyl hydroxide.A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. The parent compound is the hypothetical compound sulfurous acid.A sulfonic acid is produced by the process of sulfonation.Usually the sulfonating agent is sulfur trioxide. A particularly large scale application of this method is the production of alkylbenzenesulfonic acids.Sulfonic acids are much stronger acids than the corresponding carboxylic acids. p-Toluenesulfonic acid, with a pKa of −2.8.Sulfonic acids can be converted to esters.Sulfonic esters such as methyl triflate are considered good alkylating agents in organic synthesis.Such sulfonate esters are often prepared by alcoholysis of the sulfonyl chlorides.
