Manganese Dinitrate Hexahydrate is a highly water soluble crystalline salt composed of manganese and nitrate with formula Mn(NO3)2. In nature, manganese nitrate is found in the form of hydrates, most common is the tetrahydrate Mn(NO3)2•4H2O, but mono- and hexahydrates are also known as well as the anhydrous compound. On heating to 300°C, aqueous solutions of manganese(II) nitrate thermally decompose to form MnO2 and NO2 as products. Manganese(II) nitrate can be prepared by dissolving manganese(II) carbonate in dilute nitric acid, it can also be prepared from manganese dioxide and nitrogen dioxide Manganese Dinitrate is an important intermediate in the production of high-purity manganese oxides and is also used in the preparation of colorants for the ceramics industry.

Ponceau 3R is an azo dye that once was used as a red food colorant. Ponceau 3R is carcinogenic in rats following its oral administration, producing liver-cell tumours. It also produced bladder tumours in mice following its implantation in the urinary bladder. The oral study in mice was considered inadequate for evaluation. Ponceau 3R was reduced in vitro by Fusobacterium sp. 2, a human intestinal anaerobe, to a product which is mutagenic when metabolically activated by liver S9 preparations in the Salmonella/mammalian-microsome mutagenicity test. This mutagenic metabolite has been identified as 2,4,5-trimethylaniline.

Cobaltous formate dihydrate is a salt of cobalt which forms monoclinic crystals with space groupP21/c.

Cupric Formate (Copper(II) formate) is an inorganic salt derived from formic acid. It is used as antibacterial agent in the treatment of cellulose. Effective fungicide.

A thiomalic acid or mercaptosuccinic acid is a dicarboxylic acid containing a thiol functional group. Mercaptosuccinic acid is used in the preparation of mercaptosuccinic acid diethyl ester by reaction with ethanol. It is also used as a brightening agent in metal plating. Further, it serves as an intermediate for the synthesis of corrosion inhibitors, soil fumigants, active pharmaceutical ingredients and electroplating agents. Mercaptosuccinic acid is widely used in the synthesis of various biologically active sulfur containing compounds such as the antileukemic spiro[indoline-3,2'-thiazolidine]-2,4'-diones, and the antimicrobial and antitubercular 4-thiazolidinones. It is also used as a building block in the synthesis of novel polyanionic inhibitors of human immunodeficiency virus and other viruses, and as a starting material in the synthesis of isocysteine, an important non-proteinogenic amino acid in a potent peptide inhibitor of stromelysin. In addition, sodium salt of the anionic Au(I) complex of 2-mercaptosuccinic acid is an effective antiarthritic drug.
