  <common_name>Pyrochroite (Mn(OH)2)</common_name>
  <class>SmallMolecule</class>
  <description>Pyrochroite (Mn(OH)2) belongs to the transition metal hydroxides, a subclass of transition metal oxoanionic compounds within the inorganic compounds. This mixed metal/non-metal compound has the chemical formula H2MnO2 and an average molecular weight of 88.95 g/mol.

The substance is found in or released from ten recorded sources across various sectors. Within electrical and electronic equipment, it is associated with antennas, auxiliary devices, cores yokes or armatures, discharge lamps, and electric switches, among two other sources. In the realm of food, food processing and cookware, pyrochroite is linked to the preparation of wine or sparkling wine and fermentation processes for beer. Additionally, it is found in household cleaning and consumer products, specifically in relation to cigar cigarettes.</description>
