For chemists and laboratory professionals, selecting the appropriate pH indicator is paramount for accurate and reliable analytical results. Among the array of available indicators, Bromocresol Purple stands out due to its distinct color change and broad applicability. This article delves into why Bromocresol Purple, available from reputable manufacturers and suppliers, is a staple in many laboratory settings.

Bromocresol Purple, known chemically as 5,5′-Dibromo-o-cresolsulfonphthalein, belongs to the sulfonephthalein class of dyes. Its primary function is as a visual pH indicator, transitioning from a yellow hue in acidic conditions to a vibrant purple in alkaline conditions. This transition occurs within a specific pH range, typically cited as 5.2 to 6.8. This well-defined transition point makes it an excellent choice for monitoring reactions and solutions near neutral pH.

The utility of Bromocresol Purple extends beyond simple pH indication. In many laboratories, it is utilized for its role in the spectrophotometric determination of serum proteins, particularly albumin. This application is critical in clinical chemistry, where accurate albumin levels are vital for patient diagnosis and monitoring. By forming complexes that can be quantified spectrophotometrically, Bromocresol Purple aids in precise albumin quantification.

Furthermore, Bromocresol Purple finds application in various titration procedures. Its sharp color change allows for the accurate determination of endpoints in acid-base titrations. For researchers and procurement managers looking to buy Bromocresol Purple, understanding these applications ensures you are sourcing the correct grade and quantity for your specific needs.
