Allgemeine Beschreibung

Carbidopa is a peripheral decarboxylase inhibitor which is often formulated with levodopa for the management of the symptoms of Parkinson′s disease. Its mode of action involves the reduction of systemic production of dopamine and minimization of undesirable effects such as nausea.
Pharmaceutical secondary standard for application in quality control. Provides pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Anwendung

Carbidopa may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations by chromatography techniques.
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.

Hinweis zur Analyse

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

Sonstige Hinweise

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.
