In the realm of chemical analysis, precise measurement is paramount. pH indicators play a pivotal role in achieving this accuracy, and Bromocresol Purple stands out as a highly effective and widely utilized compound. As a leading supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality chemical reagents, including Bromocresol Purple, to support your laboratory's diverse needs.

Bromocresol Purple, identified by its CAS number 115-40-2, is a sulfonephthalein dye that exhibits a distinct color change across a specific pH range. Its primary function is as an acid-base indicator. What makes it particularly valuable is its transition range: it changes from yellow in acidic solutions to purple in alkaline solutions, with the midpoint of the transition occurring around pH 6.4. This specific pH range, typically between 5.2 and 6.8, makes it exceptionally useful for titrations where the equivalence point falls within this spectrum. The clarity of this color change allows for precise determination of endpoints, which is critical for accurate quantitative analysis.

The utility of Bromocresol Purple extends beyond simple acid-base titrations. It is also a valuable reagent in non-aqueous titrations, a technique employed when traditional aqueous solutions are not suitable or when dealing with substances that are insoluble in water. The ability to perform accurate titrations in various media enhances the versatility of this indicator. The demand for reliable chemical reagents like Bromocresol Purple is consistently high, and understanding its properties helps researchers and technicians make informed choices. For those looking to purchase Bromocresol Purple, considering the purity and consistency offered by a reputable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. is crucial.

The physical characteristics of Bromocresol Purple are also worth noting. It typically appears as a slightly yellowish rose crystal powder.
