Popis

General description

Sodium benzoate is a sodium salt of benzoic acid, that is freely soluble in water compared to benzoic acid. It is generally used as an antimicrobial preservative in cosmetics, food, and pharmaceuticals.
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Application

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

Sodium benzoate may be used as a pharmaceutical reference standard for the determination of the analyte in raw material, food, cosmetics and pharmaceutical formulations by titrimetry and liquid chromatography.

Analysis Note

These secondary standards offer multi-traceability to the US and EP primary standards, where they are available.
