一般描述
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.
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.
应用
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.
分析说明
These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.
其他说明
This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
