Cresol Red, Sodium Salt from LabChem Inc. is a versatile pH indicator provided in a water-soluble powder form. Unlike the free acid form, the sodium salt dissolves readily in aqueous solutions, making it an excellent choice for spectrophotometric pH determination and molecular biology applications, such as a tracking dye in DNA electrophoresis.
Dual Transition Ranges: Offers two distinct visual color shifts across different pH spectra:
Acidic Range: pH 0.2 (Red) to 1.8 (Yellow).
Alkaline Range: pH 7.2 (Yellow) to 8.8 (Reddish-Purple).
Enhanced Solubility: The sodium salt formulation eliminates the need for alcohol or organic solvents, reducing potential interference in sensitive chemical matrices.
Consistent Quality: Manufactured under LabChem’s rigorous quality controls to ensure high chemical purity and lot-to-lot reliability.
Safety Support: Accompanied by a dedicated Safety Data Sheet (SDS) to guide compliant handling and storage.
Safety & Storage:
Handling: Wear appropriate personal protective equipment (PPE), including nitrile gloves, safety glasses, and a lab coat.
Storage: Store in a cool, dry area in the original, tightly sealed container to prevent moisture absorption.
Professional Use: Intended strictly for professional laboratory research and industrial applications.
