Barium Diphenylamine-4-Sulphonate

Barium Diphenylamine-4-Sulphonate – High-Purity Redox Indicator for South African Labs

Barium Diphenylamine-4-Sulphonate is a highly sensitive redox indicator widely used in volumetric analysis, particularly in potassium dichromate titrations for the determination of iron, chromium, and chemical oxygen demand (COD). As a water-soluble alternative to diphenylamine, it offers sharper endpoint detection and is the preferred indicator for dichromate-based titrimetric methods in analytical and environmental laboratories.

Key Features

• Highly sensitive redox indicator – Sharp, distinct colour change from green to violet at the endpoint
• Water soluble – Easy preparation of indicator solutions without the need for sulphuric acid dissolution
• Superior to diphenylamine – More reliable endpoint detection in dichromate titrations
• High purity reagent grade – Consistent indicator performance for accurate titrimetric results
• Available in multiple pack sizes – From laboratory quantities to bulk supply

Applications

• Potassium dichromate titration for iron(II) determination
• Chemical Oxygen Demand (COD) determination in water and wastewater
• Chromium determination by titrimetric methods
• Redox titrations in analytical and environmental chemistry
• Water quality and environmental compliance testing
• Analytical chemistry and quality control laboratories
• University and teaching laboratory use

Available in laboratory and analytical grades. Supplied to analytical and environmental laboratories across South Africa and sub-Saharan Africa. Request a quote for pricing, pack sizes, or bulk orders.
