p-Toluenesulfonicacid monohydrate
p-Toluenesulfonicacid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH3C6H4SO3H. It is a White solid that is soluble in water, alcohols, and other polar organic solvents. The CH3C6H4SO2 - group is known as the tosyl group and is often abbreviated as Ts or Tos. Most often, TsOH refers to the monohydrate, TsOH.H2O.As with other sulfonicacids, TsOH is a strong organic acid. It is about one million times stronger than benzoic acid. It is one of the few strong acids that is solid and, hence, conveniently weighed. Also, unlike some strong mineral acids (especially nitric acid, sulfuric acid, and perchloric acid), TsOH is non-oxidizing. Group: Plant metabolites. Alternative Names: PTSA Monohydrate.

Product Keywords: Pharmaceutical Excipients; Excipients for Solid Dosage Form; Alitame; Sweeteners Excipients; Sweetening agent; 80863-62-3; 80863-62-3. UNII: NA. Chemical Name: L-α-Aspartyl-N-(2, 2, 4, 4-tetramethyl-3-thietanyl)-D-alanina-mide anhydrous; L-α-Aspartyl-N-(2, 2, 4, 4-tetramethyl-3-thietanyl)-D-alanina-mide hydrate. Grade: Pharmceutical Excipients. Stability and Storage Conditions: Alitame is stable at dry room temperature and degrades at high temperature or low pH. In the first stage, allose degrades to aspartic acid and alanine (under caustic conditions), and in the second stage it degrades slowly, first to β-aspartic acid isomers and then to aspartic acid and alanine. At pH 5 - 8, the half-life of alose solution at 23°C is about 4 years. At pH 2, the half-life of allose solution at 23°C is 1 year. Allocate should be kept in an airtight container in a cool and dry place. Source and Preparation: Alitame can be synthesized in a variety of ways. For example, dissolve 3- (d-alanamide) -2, 2, 4, 4-tetramethylthiocentine (thietane) in water, then add L-aspartic acid n-thiocarboxylic anhydride in sections, stir vigorously, maintain pH 8.5 - 9.5, then adjust pH to 5.5. P-toluenesulfonicacid monohydrate was added slowly over a period of more than one hour. Filter and collect the precipitated toluene sulfonate. To obtain ali
