Description

General description

Guaifenesin is an expectorant, widely used in the treatment of cough. Its mode of action involves the alleviating of cough discomfort by increasing sputum volume and decreasing its viscosity, thus resulting in effective cough.
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

Guaifenesin may be used as a reference standard in determining the concentration of guaifenesin present in pharmaceutical formulations and human plasma using colorimetric technique and high performance liquid chromatography (HPLC), respectively. It may also be used pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using reversed-phase high-performance liquid chromatography technique.

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 USP, EP (PhEur) and BP primary standards, where they are available.

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.
