Description

General description

Certified pharmaceutical secondary standards for application in quality control provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to in-house working standards.
Triclosan is a non-ionic broad spectrum antibacterial and antifungal agent, used in personal care products such as antiseptic soaps, toothpastes, fabrics and plastics.

Application

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.

Triclosan may be used as a pharmaceutical reference standard for the determination of the analyte in waste water samples and food stuffs by various chromatography methods.

A component of cefsulodin-irgasan-novobiocin selection medium for Yersinia, a human pathogen that may contaminate animal-source food products.

Biochem/physiol Actions

It is an inhibitor of the enoyl-ACP (acyl-carrier protein) reductase component of type II fatty acid synthase (FAS-II) in bacteria and Plasmodium. It also inhibits mammalian fatty acid synthase (FASN), and may have anticarcinogenic activity.

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.
