Allgemeine Beschreibung

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. Cyclohexane is a nonpolar, flammable liquid that belongs to the group of cycloalkanes. In general, cyclohexane is obtained by hydrogenation of benzene and predominately used in the nylon industry. It also finds application in pharmaceutical applications.

Anwendung

Cyclohexane can be used as a pharmaceutical reference standard for residual solvent analysis in pharmaceutical formulations and raw materials by gas chromatography.
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.

Hinweis zur Analyse

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