Pyrocatechol Violet Price & Suppliers in India

Pyrocatechol Violet (CAS 115-41-3) is a dark brown crystalline powder belonging to the sulfonephthalein group. It functions primarily as a pH-sensitive indicator and a chelating agent that forms stable, colored complexes with metal ions such as aluminum, bismuth, and thorium, making it indispensable in analytical chemistry.

In the Indian market, this chemical is highly sought after by academic research institutions, pharmaceutical quality control laboratories, and industrial water treatment facilities. It is frequently employed in the standardization of EDTA solutions and the monitoring of heavy metal concentrations in industrial effluents to ensure compliance with environmental safety standards.

When procuring Pyrocatechol Violet, buyers should prioritize suppliers who provide a Certificate of Analysis (CoA) confirming sensitivity tests for specific metal ions. Given its sensitivity to moisture and light, sourcing from vendors with robust cold-chain or climate-controlled warehousing in industrial hubs like Mumbai, Ahmedabad, or Hyderabad is recommended to ensure product integrity.
