In the realm of clinical diagnostics and biochemical research, precise measurement of key biomarkers is fundamental. Bromocresol Purple stands out as a critical reagent, particularly for its application in the determination of serum albumin. For laboratory managers and research scientists, understanding the scientific principles behind this indicator and how to source it effectively is paramount for ensuring accurate and reliable results.

Bromocresol Purple, identified by CAS number 115-40-2, is a triphenylmethane dye that functions as a pH indicator. Its unique molecular structure allows it to undergo a reversible color change in response to alterations in hydrogen ion concentration. Specifically, it transitions from a yellow hue at pH values below 5.2 to a purple color at pH values above 6.8. This well-defined pH transition range is the foundation of its utility in various analytical techniques.

One of the most significant applications of Bromocresol Purple is in the spectrophotometric determination of serum albumin. This method leverages the dye's ability to bind to albumin, a key protein in blood plasma responsible for maintaining osmotic pressure and transporting various substances. When Bromocresol Purple binds to albumin, it forms a complex that absorbs light at a specific wavelength. By measuring the intensity of this absorption, scientists can quantify the concentration of albumin in a sample.

The effectiveness of this assay relies heavily on the purity and consistency of the Bromocresol Purple used. Impurities or variations in dye content can lead to inaccurate readings, potentially impacting patient diagnoses or research conclusions. Therefore, when procuring this reagent, laboratory professionals often search for terms like 'high purity bromocresol purple' or 'bromocresol purple for albumin determination'. Sourcing from a reputable manufacturer is crucial to guarantee the required quality.

The scientific community often seeks information on the 'price of bromocresol purple' when planning experiments or ensuring budget allocation for laboratory supplies. Engaging with dedicated chemical suppliers allows for competitive pricing, especially for bulk purchases required by diagnostic labs or research institutions. Furthermore, specifying 'bromocresol purple supplier' in search queries helps identify reliable sources.

Beyond albumin assays, the pH-indicating properties of Bromocresol Purple also lend themselves to other applications, such as in microbiology for distinguishing bacterial growth based on acid production, or as a general pH indicator in titrations. However, its role in quantitative protein analysis remains one of its most scientifically vital contributions.
