Bromophenol Blue Sodium Salt is a synthetic dye and pH indicator widely used in laboratory settings. Here's a concise breakdown:

Chemical Classification:

  • Sodium salt of Bromophenol Blue (a triphenylmethane dye).

  • Chemical formula:C19H9Br4O5S?Na (sodium salt form).

  • 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.

  • Disposal: Follow local regulations for chemical waste.

Key Notes:

  • Often mixed with other dyes (e.g., Xylene Cyanol) in loading buffers for electrophoresis.

  • Not suitable for neutral/basic pH ranges (use Bromothymol Blue or Phenolphthalein instead).
