Product Overview

Bromophenol blue indicator solution is a synthetic pH-sensitive dye widely used in laboratory settings for precise acid-base titrations and pH monitoring. This high-purity solution exhibits a distinct color transition from yellow (acidic) to blue (basic) within the pH range of 3.0 to 4.6, making it indispensable for accurate endpoint detection in volumetric analysis. The formulation is optimized for stability and consistency, ensuring reliable performance across multiple experiments. As a laboratory-grade reagent, it meets stringent quality standards, free from contaminants that could interfere with sensitive measurements. The solution is prepared in a solvent system that maintains its efficacy over extended storage periods when kept under recommended conditions. Its versatility extends to various analytical applications where precise pH determination is critical. The concentrated form allows for easy dilution as per experimental requirements while maintaining color intensity. This indicator solution is particularly valued for its sharp color change at the transition point, reducing subjective interpretation errors during titrations.

FAQs

1. What is the exact pH range where bromophenol blue changes color?

The color transition occurs between pH 3.0 (yellow) and pH 4.6 (blue), with a noticeable purple intermediate at the transition point.

2. Can this indicator be used with non-aqueous solvents?

While primarily designed for aqueous systems, bromophenol blue can be used in some organic solvents, though the color transition range may shift slightly.

3. What’s the shelf life of this indicator solution when stored properly?

When stored in a cool, dark place with the container tightly sealed, the solution maintains its efficacy for up to 24 months from the date of manufacture.

4. How should this indicator be disposed of after use?

Small quantities can be neutralized and disposed of according to standard laboratory chemical waste protocols, following local environmental regulations.
