Sodium Benzoate - AR - 500GM

Sodium Benzoate is the sodium salt of benzoic acid and is widely used as a laboratory reagent, preservative, buffer component, and chemical intermediate. AR (Analytical Reagent) grade indicates that the material is manufactured to controlled purity specifications suitable for analytical and laboratory applications.

Key product information

What does AR Grade mean?

AR = Analytical Reagent.

It is intended for laboratory and analytical work where controlled impurity levels and consistent performance are important. For a commercial listing, however, you should state the actual assay and impurity specifications from your manufacturer's CoA, rather than automatically claiming a particular purity level.

Major applications

1. Laboratory reagent
Used in analytical chemistry and general laboratory preparations.

2. Buffer preparation
Sodium benzoate can be used in certain buffer systems and pH-controlled formulations.

3. Microbiology
Used in selected microbiological media and laboratory studies.

4. Pharmaceutical research
Used as an excipient/raw material in appropriate pharmaceutical formulations and R&D.

5. Food & beverage applications
Sodium benzoate is widely used as a preservative in acidic food and beverage systems—but AR-grade material should not automatically be marketed as food grade. Food applications require the appropriate food-grade specification and regulatory compliance.

6. Chemical synthesis
Can be used as a starting material or reagent in chemical research and synthesis.
