About Sodium p-toluenesulfonate

Sodium p-toluenesulfonate is a toluenesulfonate ester used in organic chemical reactions as an alkylating agent, non-oxidizing catalyst, intermediate for the synthesis of biologically active compounds, and supporting electrolyte for depositing polypyrrole membranes. American Elements can produce most materials in high purity and ultra high purity (up to 99.99999%) forms and follows applicable ASTM testing standards; a range of grades are available including Mil Spec (military grade), ACS, Reagent and Technical Grade, Food, Agricultural and Pharmaceutical Grade, Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia). We can also produce materials to custom specifications by request, in addition to custom compositions for commercial and research applications and new proprietary technologies. Typical and custom packaging is available, as is additional research, technical and safety (MSDS) data.

Sodium

11 Na 22.989769280 Sodium

See more Sodium products. Sodium (atomic symbol: Na, atomic number: 11) is a Block D, Group 5, Period 4 element with an atomic weight of 22.989769. The number of electrons in each of Sodium's shells is [2, 8, 1] and its electron configuration is [Ne] 3s¹. The sodium atom has a radius of 185.8 pm and a Van der Waals radius of 227 pm. Sodium was discovered and first isolated by Sir Humphrey Davy in 1807. In its elemental form, sodium has a silvery-white metallic appearance. It is the sixth most abundant element, making up 2.6 % of the earth's crust. Sodium does not occur in nature as a free element and must be extracted from its compounds (e.g., feldspars, sodalite, and rock salt). The name Sodium is thought to come from the Arabic word suda, meaning "headache" (due to sodium carbonate's headache-alleviating properties), and its elemental symbol Na comes from natrium, its Latin name.

Sulfur

16 S 32.065000000 Sulfur

See more Sulfur products. Sulfur (or Sulphur) (atomic symbol: S, atomic number: 16) is a Block P, Group 16, Period 3 element with an atomic radius of 32.066. Sulfur Bohr Model The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electron configuration is [Ne] 3s² 3p⁴. In its elemental form, sulfur has a light yellow appearance. The sulfur atom has a covalent radius of 105 pm and a Van der Waals radius of 180 pm. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, and epsom salts. Sulfur has been known since ancient times but was not accepted as an element until 1777, when Antoine Lavoisier helped to convince the scientific community that it was an element and not a compound.
