Analysis Note

These secondary standards offer multi-traceability to the US and EP primary standards, where they are available.

Application

Dequalinium chloride may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by high performance liquid chromatography (HPLC).
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.

General description

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.
Dequalinium chloride (DECA) is a cationic, lipophilic mitochondrial toxin which can act as a cyctotoxic agent on the mitochondrial membrane of specific epithelial carcinoma cells, by inhibiting the cellular energy production. It can have useful applications in cancer therapy.

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.
