Description

General description

Toluene is a non-polar organic solvent and methyl derivative of benzene. As per USP and EP, it belongs to the Class 2 category of organic solvents and has limited application in the synthesis of pharmaceuticals, due to its moderate toxicity.
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.

Toluene may be used as a pharmaceutical solvent reference standard for the determination of the analyte in bulk drug and pharmaceutical formulations by gas chromatography.
