Glucose sensors work by colorimetrically monitoring the formation of this compound when glucose is oxidized.
Glucose sensors work by colorimetrically monitoring the formation of this compound when glucose is oxidized. Piranha solution contains it and sulfuric acid. This compound catalyzes the second step of hydroborationÂ–oxidation. A mixture of iron and this compound is used to decontaminate halogenated organic waste in water. This compound forms when long-chain fatty acids are dehydrogenated, but it is immediately (*)  disproportionated in cells from a negative-one oxidation state to compounds with zero and negative-two oxidation states by the enzyme catalase. Shining UV light on this compound gives two hydroxyl radicals, so it must be stored in opaque brown bottles, often in a 3-percent aqueous solution, at which point it is used as an antiseptic. For 10 points, name this compound which has formula H2O2.
