Popis

General description

o-Xylene is a nonoxygenated, homocyclic aromatic compound that occurs as a constituent of petroleum. It belongs to the class of volatile organic compounds (VOCs) having vapor pressure high enough to vaporize under normal conditions and enter into the atmosphere. It is found to be relatively water-soluble and suspected to have carcinogenic properties.
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.

Analysis Note

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