Products Description of Maltose CAS#69-79-4Maltose is the abbreviation of maltobiose, also known as D-maltose and maltose. A disaccharide formed by connecting, condensing, and dehydrating two molecules of α-D-glucose through α-1,4 glycosidic bonds. There is also a free hemiacetal hydroxyl group in the molecule, which is a reducing sugar. Like glucose, it can make Doron's reagent and Fehling's reagent react positively.

Sodium Sulfide CAS#1313-82-2Product Description:  Sodium sulfide is the chemical compound with the system Na₂S, or greater many times its hydrate Na₂S·9H₂O. Both are colorless water-soluble salts that supply strongly alkaline solutions. When uncovered to moist air, Na₂S and its hydrates emit hydrogen sulfide, which smells like rotten eggs. Sodium sulfide, anhydrous is a yellow to brick pink crystalline mass or fused solid. If uncovered to moist air, it absorbs moisture from the air, and it is in charge to spontaneous heating and might also motive ignition of close by flamable material.
