Beschreibung

General description

Benzoic acid is a volumetric standard produced under rigorous conditions and qualified with the highest possible precision. Its content determination and homogeneity assessment are performed by volumetric neutralization as the primary analysis method.

Application

It is used as a reference material for the standardization of volumetric solutions in alkalimetric titrations.

Features and Benefits

• Available as a solid in a secure glass bottle to ensure its stability for the entire shelf life until opened.
• Traceable to NIST SRM
• High-quality offering accurate titer determinations
• Accompanied by a certificate of analysis (CoA)
