m-Cresol Purple Indicator, 0.1% Aqueous
Manufacturer: LabChem Inc.
This m-Cresol Purple (0.1% Aqueous) solution from LabChem Inc. is a specialized sulfonphthalein dye used primarily in acid-base titrations and colorimetric pH determinations. What makes m-Cresol Purple unique is its dual transition range, allowing researchers to monitor both highly acidic and slightly alkaline environments with a single reagent. Commonly utilized in oceanography for measuring seawater pH and in various industrial chemical analyses, this aqueous formulation is ready to use, ensuring consistency in your colorimetric results without the need for manual dissolution and stabilization.
Description
Key Functional Benefits:
- Dual-Stage Monitoring: Eliminates the need for multiple indicators in complex experiments that transition across broad pH spectrums
- Aqueous Formulation: Safer and easier to handle than alcohol-based indicators, with reduced evaporation and flammability risks
- High Contrast: Provides sharp, distinct color changes (Red $\rightarrow$ Yellow $\rightarrow$ Purple) that are easily detectable by the naked eye or spectrophotometric equipment
- Standardized Purity: LabChem Inc. ensures minimal impurities, providing a reliable pKa value for accurate colorimetric calculations
Safety & Storage Insights:
- Storage: Store at room temperature (15°C - 30°C) in a tightly sealed container. Keep away from direct sunlight to prevent photodegradation of the dye
- Seawater Analysis: In oceanography, m-Cresol Purple is the preferred indicator for "spectrophotometric pH" due to its well-characterized temperature and salinity dependence
- Handling: While this is an aqueous solution, the dye can cause significant staining on skin and lab surfaces. Always wear appropriate PPE (gloves and goggles) during use
