Description

General description
Sorbic acid is a short-chained unsaturated aliphatic carboxylic fatty acid, that is used as an antimicrobial preservative in a wide range of foods, drugs, and cosmetic products.
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.
Sorbic acid may be used as a pharmaceutical reference standard for the determination of the analyte in raw material, food and pharmaceutical formulations by titrimetry and high performance liquid chromatography.
Analysis Note
These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.

Application Note

Sorbic acid pharmaceutical secondary standard is a certified reference material for analytical quality control of sorbic acid in pharmaceutical-related samples and formulations. Sorbic acid is an unsaturated carboxylic acid widely used as a preservative, and its determination can require an authenticated calibration or comparison material. This secondary standard provides a traceable reference for laboratory methods including high-performance liquid chromatography and gas chromatography. It is traceable to USP reference standard 1615956, while the certified value and uncertainty for each lot are documented in the corresponding certificate of analysis. For quantitative methods, determine the working concentration from the certified lot-specific purity and apply a documented dilution procedure. Use suitable containers, solvents and handling conditions to maintain solution integrity. The neat 1 g format is intended for reference-standard preparation and system suitability or method verification, not for bulk preservative formulation or routine ingredient manufacture.
