Applications
1. Pet Food And Livestock Premix supplies organic sulfur in pet and livestock rations, and the crystalline form mixes evenly through dry premixes so nutrient levels stay consistent from bag to bag.
2. Organic Synthesis Feedstock supplies a stable sulfur unit that can be deprotonated and used as a nucleophile in substitution chemistry, giving process chemists an inert and easy to handle organosulfur building block.
3. Fortified Foods And Beverages added to processed foods and beverage systems as an organic sulfur source, and its high water solubility lets formulators carry it in drinks as easily as in dry premixes.
4. Cosmetic And Personal Care Bases dissolves readily in the water phase, which suits skin care and personal care systems where formulators want a small polar sulfur compound to carry without a heavy solvent or an oil phase.
5. Laboratory And Analytical Work supplied as a crystalline solid that has served as a gas chromatography stationary phase and an analytical reagent, so labs can weigh, dissolve and standardize it without special handling.
