Description

General description

Diethyl ether is a non-polar volatile organic solvent, commonly used as an extraction solvent in liquid-liquid extraction for separation of post reaction residues from synthetic products.
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

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

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.

Other Notes

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.
