General description

Cetylpyridinum chloride is a quaternary ammonium compound and an active ingredient of antiseptic oral mouth rinses with broad spectrum antimicrobial activity. Its mode of action involves a rapid bactericidal effect on Gram-positive pathogens and a fungicide effect on certain yeasts.
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

Cetylpyridinum chloride may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical preparations 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.
