Descrizione generale

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.

Applicazioni

α-Tocopheryl acetate may be used as an internal standard in the determination of α-tocopherol in human serum or plasma samples using high performance chromatography (HPLC). It may also be used pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using spectrophotometric 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.

Risultati analitici

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

Altre note

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.

The synergistic antioxidant effects of ethanolic extracts of Centella asiatica (CE), and α-tocopherol have been studied. The types of interactions exhibited by CE and α-tocopherol combined at different ratios were measured using three assays: 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS) radical-scavenging
