CAS 7784-41-0
:Potassium dihydrogen arsenate
Description:
Potassium dihydrogen arsenate, with the chemical formula KH₂AsO₄ and CAS number 7784-41-0, is an inorganic compound that appears as a white crystalline solid. It is a salt formed from the reaction of arsenic acid with potassium hydroxide. This compound is soluble in water, making it useful in various applications, including as a reagent in analytical chemistry and as a source of arsenate ions in biological studies. Potassium dihydrogen arsenate exhibits properties typical of a dihydrogen phosphate, such as being a weak acid and having the ability to form complexes with metal ions. It is important to handle this substance with care due to the toxicity associated with arsenic compounds. In terms of stability, it is generally stable under normal conditions but should be stored in a cool, dry place away from incompatible materials. Its potential applications extend to agriculture, where it may be used as a fertilizer, although its use is limited due to environmental and health concerns related to arsenic.

Potassium dihydrogen arsenate
CAS:<p>Potassium dihydrogen arsenate is an inorganic chemical that is used as a pesticide. It prevents the synthesis of proteins by inhibiting soybean trypsin. The optimum concentration for chrysoperla is 1.6 mg/L, which has been shown to be sublethal at levels below 5 mg/L. This chemical has also been shown to have effects on light exposure and thermal expansion. Potassium dihydrogen arsenate belongs to the ferroelectric class of compounds and has a hydrogen bond with water, which may explain its uptake into plants.</p>Formula:H2AsKO4Purity:Min. 95%Molecular weight:180.04 g/mol
