The vinegar test does have important limitations and disadvantages for cervical cancer screening, as well; please refer to that section in the main Cervical_screening article. Vinegar test Vinegar test is a cervical cancer testing method that uses acetic acid, a major component of vinegar. It has been found to be useful as an effective and inexpensive screening
Cyanuric acid Cyanuric acid Cyanuric acid or 1,3,5-triazine-2,4,6-triol is a chemical compound with the formula (CNOH). Like many industrially useful chemicals, this triazine has many synonyms. This white, odorless solid finds use as a precursor or a component of bleaches, disinfectants, and herbicides. In 1997, worldwide production was 160 million kilograms. Cyanuric acid is the cyclic trimer of the elusive species cyanic acid, HOCN. The two structures shown in the infobox are tautomers that readily interconvert. However, mixture with melamine forms melamine cyanurate, which locks cyanuric acid in the tri-keto tautomer and makes melamine cyanurate insoluble in water. The triol tautomer, which
