Specification

The Manganese is an organic compound with the formula Mn. With the CAS registry number 7439-96-5, the IUPAC name of this chemical is manganese. The product's categories are Inorganics; AAS; AAS CRMsAlphabetic; AASSpectroscopy; Application CRMs; M; MA - MDSpectroscopy; Matrix Selection; Nitrate; Spectroscopy; ICP CRMsAlphabetic; ICP-OES/-MS; ICPSpectroscopy; Manganese; Metal and Ceramic Science; Metals; AA Standard SolutionsAlphabetic; NitrateSpectroscopy; Reference/Calibration Standards; Single Solution; Standard Solutions; Catalysis and Inorganic Chemistry; Chemical Synthesis; ManganeseMetal and Ceramic Science. Besides, it should be stored in a cool dry and well-ventilated place.

Preparation: this chemical can be prepared by Manganese carbonate and sulfuric acid.

Uses of Manganese: it is a metal with important industrial metal alloy uses, particularly in stainless steels. Manganese(II) ions function as cofactors for a number of enzymes in higher organisms, where they are essential in detoxification of superoxide free radicals. The element is a required trace mineral for all known living organisms. In larger amounts, and apparently with far greater activity by inhalation, manganese can cause a poisoning syndrome in mammals, with neurological damage which is sometimes irreversible.

When you are using this chemical, please be cautious about it as the following:
It is highly flammable and toxic by inhalation, in contact with skin and if swallowed. Please take off immediately all contaminated clothing. It contacts with water liberates extremely flammable gases and can cause burns. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Besides, this chemical is irritating to to eyes and skin. When you are using it, wear suitable gloves and eye/face protection. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible).

You can still convert the following datas into molecular structure:
(1)SMILES: [Mn]
(2)InChI: InChI=1/Mn
(3)InChIKey: PWHULOQIROXLJO-UHFFFAOYAG
(4)Std. InChI: InChI=1S/Mn
