The precision and accuracy of chemical analyses are heavily dependent on the quality and reliability of the reagents used. Bromocresol Purple (CAS: 115-40-2), a prominent pH indicator, plays a pivotal role in ensuring these standards are met across a wide spectrum of industrial and scientific applications. For procurement managers and chemists operating in B2B environments, understanding the technical specifications and sourcing strategies for this compound is crucial. This article highlights the key attributes of Bromocresol Purple and provides guidance on how to efficiently buy this essential chemical from a reputable Chinese manufacturer.

Bromocresol Purple, a member of the sulfonephthalein family of dyes, is characterized by its ability to indicate pH changes through distinct color shifts. Its operational pH range is between 5.2 (yellow) and 6.8 (purple). This well-defined transition makes it an excellent visual aid for acid-base titrations, facilitating accurate determination of reaction endpoints. Its chemical formula is C21H16Br2O5S, with a molecular weight of 540.22 g/mol. The compound is typically supplied as a slightly yellow crystalline powder, with a melting point around 240°C (with decomposition). Its solubility in ethanol and insolubility in water are also important physical properties to consider during its application.

The applications of Bromocresol Purple are diverse and impactful. It serves as a critical reagent in analytical laboratories for routine pH testing and titrimetric analyses. In the field of environmental science, it is utilized for monitoring water quality and assessing soil pH levels, essential for agricultural and ecological studies. Furthermore, in the healthcare sector, Bromocresol Purple is employed in specific diagnostic tests, such as the determination of serum protein levels or its use in identifying certain types of bacterial growth based on pH changes. Its consistent performance and clear visual cues make it a valuable asset in these demanding fields.
