Descrição

Descrição geral

Certified 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. tert-Butyl methyl ether (MTBE) is a gasoline additive. It is a commonly used organic solvent that can be synthesized by acid catalyzed reaction between methanol and isobutene. It is also an effective alternative to lead containing additives for enhancing the octane rating of gasoline.

Aplicação

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.

Nota de análise

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