CAS Number: 62625-28-9.

Key Properties:

pH Indicator:

Transition range: pH 3.0 (yellow) to 4.6 (blue-purple).
Used to monitor acidity in titrations or buffer systems.
Electrophoresis Tracking Dye:

Added to DNA/RNA/protein samples to visualize migration progress in agarose or polyacrylamide gels.
Migrates at ~300–500 bp (DNA) or ~3–4 kDa (proteins), depending on gel conditions.
Solubility:

Highly water-soluble (due to sodium salt form) compared to the free acid.

Applications:

Molecular Biology: Tracking dye in gel electrophoresis.
Analytical Chemistry: pH indicator in titrations or buffer prep.
Microscopy: Staining agent for biological specimens (less common).

Safety & Handling:

Hazards: May cause mild skin/eye irritation. Avoid inhalation.
Precautions: Use gloves, lab coat, and eye protection.
