General description

Cyanuric acid (CYA) is a triazine industrial chemical, used in production of scouring powders, household bleaches, industrial cleansers, and automatic dishwasher compounds. It is also used as stabilizers in swimming pools which helps in preventing destruction of chlorine due to UV. It has a weak acid taste and is sparingly soluble in cold water.

Application

Cyanuric acid may be used as an analytical reference standard for the quantification of the analyte in the following:
  • Milk and milk products using gas chromatography with tandem mass spectrometric (GC-MS/MS) detection.
  • Human urine samples and infant formula using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS).

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
