| Analysis Note: | These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available. |
| 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. |
| 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. |
| Biochem/physiol Actions: | 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. |

| 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. 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. |
