Product Overview

Sulphuric Acid 98% Extra Pure (CAS No. 7664-93-9) is a highly concentrated sulphuric acid reagent at the specified 98% strength. Sulphuric acid is a strong diprotic acid with pronounced protonating, dehydrating and acid-catalytic behaviour and can participate in sulphonation, esterification, digestion and inorganic salt formation.

The Extra Pure grade is intended for general acidification, dehydration, digestion, reagent preparation and preparative laboratory chemistry. Its strong diprotic acidity makes it useful across inorganic, organic and materials-related procedures requiring concentrated sulphuric acid.

Typical Applications

• Acidification of laboratory reaction and reagent systems.
• Acid-catalysed esterification and related synthesis.
• Sulphonation and strongly acidic reaction studies.
• Dehydration and carbonisation research.
• Inorganic sample digestion and decomposition studies.
• Preparation of sulphate salts and acidic reagent mixtures.

Common Synonyms

• Sulfuric acid
• Oil of vitriol

Storage Conditions

Keep tightly closed to limit uncontrolled moisture exchange and external contamination that could change acid concentration or purity. Maintain clean handling and prevent introduction of materials that could contaminate the concentrated reagent.
