General description

Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to pharmacopeia primary standards. Warfarin Sodium is an anticoagulant rodenticide, commonly used for the control of rodents such as rats, mice, etc. in surroundings, commercial and industrial sites.


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.
Warfarin Sodium may be used pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using square-wave adsorptive cathodic stripping voltammetry.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP 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.
