In the realm of analytical chemistry, precision and reliability are non-negotiable. For scientists and lab technicians, having access to high-quality reagents is the cornerstone of accurate experimental outcomes. Among these essential chemicals, Cresol Purple (CAS 2303-01-7) plays a crucial role as a pH indicator. Its specific properties and applications make it indispensable for various laboratory procedures.
Cresol Purple, scientifically known as m-Cresol Purple, is characterized by its molecular formula C21H18O5S and a molecular weight of 382.43. As a supplier of fine chemicals, we understand the importance of its physical attributes. It typically presents as a purple to dark purple crystalline powder. For research scientists and product formulators, sourcing this reagent means looking for consistent appearance and purity to ensure predictable results in their formulations and analyses.
The primary utility of Cresol Purple lies in its function as an acid-base indicator. It exhibits distinct color changes within specific pH ranges, serving as a visual cue for the endpoint of titrations or the pH of a solution. The acidic zone shows a change from red to yellow between pH 1.2 and 2.8, while the alkaline zone displays a transformation from yellow to purple between pH 7.6 and 9.2. This dual-range capability makes it exceptionally versatile.
For procurement managers in R&D departments, finding a dependable manufacturer and supplier for Cresol Purple is a strategic imperative. This ensures not only competitive pricing but also a stable supply chain, crucial for uninterrupted research and development cycles. Companies seeking to purchase Cresol Purple should look for suppliers who can provide detailed specifications, including purity (≥98%) and low residue on ignition, to guarantee performance in sensitive analytical applications.
The application of Cresol Purple extends to detecting the alkalinity of water, a common task in environmental science and water treatment industries. Its reliable performance in these tests makes it a frequently sought-after chemical. By understanding the specifications and applications of Cresol Purple, businesses can make informed purchasing decisions, ensuring they acquire a reagent that meets their exact analytical needs and contributes to the success of their projects.
