(S)-(-)-2-Methyl-2-propanesulfinamide is generally immediately available in most volumes. High purity, submicron and nanopowder forms may be considered.American Elements produces to many standard grades when applicable, 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)and follows applicable ASTM testing standards.Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.
Sulfur is a Block P, Group 16, Period 3 element. The number of electrons in each of Sulfur's shells is 2, 8, 6 and its electronic configuration is [Ne]3s2 3p4. In its elemental form sulfur's CAS number is 7704-34-9. The sulfur atom has a radius of 100pm and it's Van der Waals radius is 180pm. Sulfur is a crucial element for all life and serves as both fuels and respiratory (oxygen-replacing) materials for simple organisms. In nature, sulfur can be found in hot springs, meteorites, volcanoes, and as galena, gypsum, Epsom salts, and barite. Sulfur, when organically bonded, is a component of all proteins, as the amino acids methionine and cysteine. In organic form, Sulfur is present in the vitamins thiamine and biotin. Sulfur is also a vital part of many enzymes and also in antioxidant molecules like glutathione and thioredoxin.Sulfur is available as compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity). Sulfur has been known since ancient times but was not accepted as an element until 1777. Antoine Lavoisier helped to convince the scientific commuity that sulfus is an element and not a compound.
