Description

General description
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
Benzoic acid may be used as a reference standard in determining the concentration of benzoic acid in food and milk samples using high performance liquid chromatography coupled with photodiode array detector (HPLC).
Analysis Note
These secondary standards offer multi-traceability to the USP and EP (PhEur) primary standards, where they are available.

FAQs

Question: What grade is supplied?

Answer:The product is a pharmaceutical secondary standard and certified reference material.

Question: What quantity is included?

Answer:This configuration contains 1 g.

Question: What is the molecular weight?

Answer:Benzoic acid has a molecular weight of 122.12 g/mol.

Application Note

Benzoic acid is supplied as a pharmaceutical secondary standard and certified reference material for quantitative analytical work. This configuration contains 1 g of neat material. Benzoic acid has the formula C₆H₅COOH, molecular weight 122.12 g/mol, and CAS number 65-85-0. The standard provides a convenient working reference for pharmaceutical quality-control laboratories that need traceable calibration without preparing an in-house secondary standard from primary material. It is suitable for chromatographic methods such as HPLC and can support identity testing, assay calibration, method development, release testing, and other validated analyses of benzoic acid in formulations or raw materials. Certified lot values and traceability information are supplied with the associated certificate.
