Calmagite (CAS 3147-14-6) is a metalochromic indicator widely used in complexometric titrations for calcium and magnesium determination. Key parameters:

Comparative Analysis with Similar Indicators

Industrial & Scientific Applications

1. Water Hardness Analysis

EPA-approved method for municipal water treatment plants to measure Ca²⁺/Mg²⁺ concentrations with ±0.5% accuracy.

2. Pharmaceutical Quality Control

Used in USP compliance testing for mineral supplements and antacid formulations.

3. Food Industry

Determination of calcium content in dairy products (AOAC Method 935.42).

4. Research Applications

Essential in metalloprotein studies and nanomaterial synthesis quality control.

Optimal Usage Protocol

Solution Preparation

1. Dissolve 0.2g Calmagite in 100ml ethanol (ACS grade)
2. Filter through 0.45μm membrane
3. Store in amber glass at 4°C (6-month stability)

Titration Procedure

1. Adjust sample pH to 10.0 with NH₃/NH₄Cl buffer
2. Add 2-3 drops indicator
3. Titrate with 0.01M EDTA until color shifts from red to blue
