Beschreibung

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. Pyridine is a heterocyclic aromatic compound that is a commonly used solvent in organic and inorganic chemistry. Its weakly basic nature allows it to act as a proton acceptor in acid base reactions, and to form salts with strong acids. In the acylation of alcohols, pyridine can act as a nucleophilic catalyst.

Anwendung

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 and EP primary standards, where they are available.
