For any chemist or laboratory manager, the selection of the right analytical reagents is paramount to achieving accurate and reproducible results. Among these essential tools, indicators play a crucial role, signaling the completion of a chemical reaction. Today, we'll delve into the significance and applications of Pyrocatechol Violet (CAS 115-41-3), a widely used indicator, and discuss why sourcing it from a reliable manufacturer and supplier in China, like NINGBO INNO PHARMCHEM CO.,LTD., is a strategic advantage.
Understanding Pyrocatechol Violet's Role
Pyrocatechol Violet, also known by synonyms like Catechol Violet, is a chemical compound that functions exceptionally well as both a metal complexometric indicator and a pH indicator. Its molecular formula is C19H14O7S, and its CAS number is 115-41-3. Typically appearing as a red-brown crystalline powder, it is readily soluble in water and alcohols, which simplifies its use in various titration setups. The key to its efficacy lies in its ability to form distinct, colored complexes with various metal ions. This property allows chemists to precisely pinpoint the endpoint of a complexometric titration, a technique vital for determining the concentration of metal ions in a sample.
Key Applications and Advantages
The primary application for Pyrocatechol Violet is in metal complexometric titrations, especially those involving EDTA (ethylenediaminetetraacetic acid). It provides a clear visual cue when all metal ions have been complexed by the titrant. Beyond this, its utility extends to pH indication. It exhibits a color transition range from pH 6.0 (yellow) to 9.0 (purplish-red). This dual functionality makes it a versatile and cost-effective choice for laboratories needing reliable analytical tools. For procurement managers looking to buy this reagent, understanding these applications ensures they are acquiring the right product for their specific needs.
Why Choose a Chinese Manufacturer for Pyrocatechol Violet?
The chemical industry in China has grown exponentially, with many manufacturers now adhering to stringent international quality standards. When you purchase Pyrocatechol Violet from a reputable Chinese supplier, you gain access to:
For R&D scientists and product formulators, procuring high-quality Pyrocatechol Violet (CAS 115-41-3) is essential for the success of their experiments and product development. By partnering with a trusted manufacturer and supplier in China, you can confidently buy the reagents needed to achieve precise analytical outcomes.
