1. Product Overview & Specifications

Methyl Orange (CAS 547-58-0) is a pH-sensitive azo dye widely used as an acid-base indicator. Key specifications include:

2. Key Applications & Use Cases

Laboratory Titrations

Primary use in strong acid-strong base titrations (0.1M-1M concentrations). Transition from red (pH ≤3.1) to yellow (pH ≥4.4) provides clear endpoint detection.

Industrial Water Treatment

pH monitoring in wastewater systems, particularly effective in:

• Cooling tower management
• Effluent neutralization processes
• Corrosion prevention systems

3. Practical Usage Scenarios

Standard Laboratory Protocol

Preparation: 0.1% aqueous solution (1g Methyl Orange + 1L DI water). Shelf life: 24 months at 15-25°C.

Educational Demonstration

Classroom experiment showing pH-dependent color changes:

1. Add 2 drops to 50ml 0.1M HCl (red)
2. Gradually titrate with 0.1M NaOH
3. Observe transition at pH 4.4

4. Customer Success Stories
