SULPHANILIC ACID, AR GRADE

Sulphanilic Acid, AR Grade is a high-purity compound commonly used in the quantitative determination of nitrate and nitrite ions. In the solid state it has a stable internal ionic character, which is responsible for its comparatively high melting temperature and reproducible behavior in the analytical process. This AR grade material is manufactured under strict control over impurities like chloride, sulphate, copper, iron, and heavy metals, for accuracy and least interference in sensitive application. It provides reliable quality, consistency and traceability to lot for precise analytical use with an assay of not less than 99.0%.

An analytical reagent grade aromatic sulphonic acid supplied as greyish-white crystals or powder.
