In the scientific and industrial sectors, the demand for reliable analytical reagents is constant. Pyrocatechol Violet, bearing the CAS number 115-41-3, is a key compound frequently sought after for its critical role as a metal complexometric indicator and pH indicator. For procurement managers and product formulators, understanding where and how to buy this reagent is essential for ensuring both quality and cost-effectiveness. This guide focuses on the benefits of sourcing Pyrocatechol Violet from established Chinese manufacturers and suppliers.

The Indispensable Role of Pyrocatechol Violet

Pyrocatechol Violet, a red-brown crystalline powder, is prized for its ability to form distinct colored complexes with various metal ions. This property makes it invaluable for complexometric titrations, where it signals the precise endpoint of a reaction, thereby ensuring accurate quantitative analysis. Its solubility in water and alcohols further facilitates its use in common laboratory settings. Beyond titration, its pH indicator properties, with transitions typically observed between pH 6.0 and 9.0, add to its versatility, making it a staple in many analytical chemistry workflows.

Ensuring Quality When You Buy Pyrocatechol Violet

The effectiveness of Pyrocatechol Violet hinges on its purity. Factors that can impact its performance include contaminants that might interfere with color changes or complex formation. Therefore, when making a purchase, it is crucial to:

  • Verify Manufacturer Specifications: Always review the product’s assay purity, solubility, and any specific impurity profiles provided by the supplier.
  • Seek Reputable Suppliers: Partnering with well-established companies that have a track record of quality and reliability is paramount.
  • Request Samples: For significant orders, obtaining samples for in-house testing can confirm suitability and performance before committing to a large purchase.

The Advantage of Chinese Chemical Suppliers
