Agaric acid (CAS 666-99-9)

Agaric acid sesquihydrate is an organic compound that originates from various mushroom species, including those in the Agaricus genus, from where it gets its name. The term "sesquihydrate" in the name suggests that for every molecule of agaric acid, there are one and a half (or 1.5) molecules of water. This is a less common level of hydration but is seen in some chemical compounds. The water molecules are typically incorporated into the crystal structure of the compound, and this level of hydration can influence the compound′s physical properties, such as its solubility and melting point. Agaric acid itself is a fatty acid, a type of organic compound that has a carboxyl group (-COOH) at one end and a long hydrocarbon chain at the other end. Fatty acids are key components of many biological structures and systems. In its physical form, agaric acid sesquihydrate is typically a white or off-white crystalline powder. It is primarily used in research applications, particularly in studies related to organic and natural products chemistry. It′s also utilized in the study of fungi and their bioactive compounds since fungi produce a wide variety of metabolites with diverse chemical structures.
