Description

Description générale

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.
β-Carotene is an antioxidant and is one of the most important carotenoids and a source of vitamin A. It is abundantly present in fruits and vegetables which is also used as a food supplement and a colorant.

Application

β-Carotene may be used as a pharmaceutical reference standard for the determination of the analyte in serum, plasma samples, fruits and vegetables by various 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.

Actions biochimiques/physiologiques

The most important of the provitamins A, β-carotene can be classified as an antioxidant due to its inhibition of radical initiated peroxidation in vitro. However, in vivo it appears to act either as an antioxidant or a prooxidant depending on cellular environment. It reduces the incidence of many cancers, but enhances lung cancer incidence in smokers.

Remarque sur l'analyse

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

Autres remarques

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.
