Thin-Layer Chromatography (TLC) is an indispensable technique in organic chemistry and related fields for separating, identifying, and monitoring chemical reactions. Often, the separated compounds on a TLC plate are not visible to the naked eye. This is where visualization agents, or staining reagents, become critical. Bromocresol Green (BCG), a commonly used pH indicator with CAS number 76-60-8, is one such effective reagent, particularly useful for visualizing acidic compounds on TLC plates. Procuring high-quality Bromocresol Green from reliable chemical manufacturers is essential for successful TLC analyses.

Bromocresol Green's utility in TLC stems from its acidic nature and its characteristic color change. When used as a spray reagent or incorporated into the stationary phase, BCG helps to reveal the presence of compounds that possess acidic functional groups. Specifically, it is effective for compounds with a pKa value below approximately 5.0, such as carboxylic acids and sulfonic acids. After the compounds are separated on the TLC plate, the plate is treated with Bromocresol Green. Acidic compounds, upon interaction with the dye, often cause a localized change in color, making them visible as distinct spots against the background. Researchers frequently buy Bromocresol Green for its affordability and effectiveness in this visualization role.

The mechanism behind BCG's effectiveness in TLC involves its ionization properties. In its acidic form, Bromocresol Green is yellow, but it turns blue in a basic environment. When applied to a TLC plate, the acidic analytes can either alter the local pH or react with the dye, causing a color shift that highlights their position. This provides a simple yet powerful method for qualitative analysis, assisting chemists in confirming the presence of target compounds or monitoring the progress of a reaction. When considering purchasing Bromocresol Green, understanding the price from various suppliers, especially those with manufacturing capabilities in China, is a common practice to ensure the best value.
