Cyanuric acid, also known as 1, 3, 5-triazine-2, 4, 6-triol is a chemical compound that is commonly used as a chlorine stabilizer in swimming pools. However, there are several synonyms for cyanuric acid, including isocyanuric acid, tri-s-triazinetrione, and 2, 4, 6-trihydroxy-1, 3, 5-triazine. These terms all refer to the same chemical compound and can be used interchangeably in most situations. Other related compounds include melamine cyanurate and melamine isocyanurate, which are also used as stabilizers in various industrial processes. Regardless of the terminology used, it's important to handle cyanuric acid carefully, as it can be hazardous to human health if ingested or inhaled.
