Descrizione

Descrizione generale

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.
Citric acid is a common ingredient in pharmaceutical formulations. It finds use in antacids and dentrifices because of the effervescent effect it generates upon combination with carbonates or bicarbonates. Citric acid may also be used as a buffering agent and it assists in the dispersion of suspensions in order to ensure the stability of the active ingredients and enhance the efficacy of antioxidants.

Applicazioni

Anhydrous citric acid may be used as a reference standard in determining the concentration of citric acid present in biological fluids using spectrophotometric method.

Citric acid, Anhydrous may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and milk samples by various chromatography techniques.

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.

Risultati analitici

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
