Product Overview

Hydrochloric Acid 37% AR (CAS No. 7647-01-0) is a concentrated analytical-reagent solution of hydrogen chloride in water. It provides strongly acidic chloride media for dissolution, neutralisation, hydrolysis and sample-conditioning processes used throughout classical analytical chemistry. Its concentration makes it particularly suitable as a stock reagent for preparation of accurately diluted analytical solutions.

The AR grade is intended for wet-chemical analysis, quality-control testing and method-defined sample preparation. It supports titrimetric work, dissolution of compatible inorganic materials and preparation of chloride-rich analytical media. The analytical positioning relates to conventional reagent-quality work.

Typical Applications

• Preparation of analytical hydrochloric acid solutions
• Acid-base titration and neutralisation procedures
• Dissolution and decomposition of compatible samples
• Preparation of concentrated chloride analytical media
• Gravimetric and precipitation analysis
• Qualitative inorganic analytical procedures
• Laboratory quality-control and method verification

Common Synonyms

• Hydrochloric acid
• Hydrogen chloride solution
