Sodium p-toluenesulfonate is an organic compound with the formula CH 3 C 6 H 4 SO 3 Na. It is white, water-soluble solid. It is produced by the neutralization toluenesulfonic acid with sodium hydroxide. It is also a common product from the reactions of sodium-based reagents with toluenesulfonates. [1]
The toluenesulfonate (or tosylate) group refers to the −O−SO 2 C 6 H 4 CH 3 (–OTs) group, with an additional oxygen attached to sulfur and open valence on an oxygen. [3] In a chemical name, the term tosylate may either refer to the salts containing the anion of p -toluenesulfonic acid, TsO − M + (e.g., sodium p-toluenesulfonate ), or it ...
p-Toluenesulfonic acid (PTSA, pTSA, or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH 3 C 6 H 4 SO 3 H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. [6] The CH 3 C 6 H 4 SO 2 group is known as the tosyl group and is often abbreviated as Ts or Tos.
The sulfonate ion. In organosulfur chemistry, a sulfonate is a salt, anion or ester of a sulfonic acid.Its formula is R−S(=O) 2 −O −, containing the functional group −S(=O) 2 −O −, where R is typically an organyl group, amino group or a halogen atom.
Diazald (N-methyl-N-nitroso-p-toluenesulfonamide) is used as a relatively safe and easily handled precursor to diazomethane, which is toxic and unstable. [2] Diazald has become the favored commercially available precursor for the synthesis of diazomethane, compared to reagents like N-methyl-N-nitrosourea and N-methyl-N'-nitro-N-nitrosoguanidine, which are less thermally stable and more toxic ...
New research has found that about 2.2 million new diagnoses of type 2 diabetes and 1.2 million new cases of cardiovascular disease may be attributed to sugar-sweetened sodas and juices each year.
By Steve Holland and David Brunnstrom. WASHINGTON (Reuters) -U.S. President-elect Donald Trump has invited Chinese President Xi Jinping and other foreign leaders to his inauguration next month in ...
Hippuric acid has long been used as an indicator of toluene exposure; [14] however, there appears to be some doubt about its validity. [15] There is significant endogenous hippuric acid production by humans; which shows inter- and intra-individual variation influenced by factors such as diet, medical treatment, alcohol consumption, etc. [15] This suggests that hippuric acid may be an ...
