Popis

General description

Adenosine is a purine nucleoside and a building block of RNA and many other biomolecules such as adenosine triphosphate and nicotinamide adenine dinucleotide. In the extracellular space, ecto-5′-nucleotidase (CD73) dephosphorylates adenosine triphosphate (ATP) to produce adenosine. Adenosine has four receptors namely A1R, A2AR A2BR and A3R. Adenosine plays a key role in the osteogenic differentiation. A1R induces osteoclast differentiation and A2AR induces osteoblast differentiation.

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.

Application

Adenosine may be used as a pharmaceutical reference standard for the quantification of the analyte in infusion solutions using high-performance liquid chromatography technique and capillary electrophoresis.

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.

Biochem/physiol Actions

Endogenous neurotransmitter at adenosine receptors. Cardioprotective effects may relate to activation of A₁ adenosine receptors. The antiplatelet and anti−inflammatory actions of adenosine appear to be mediated via the A₂ adenosine receptor. In contrast, adenosine appears to be a pro-inflammatory mediator in asthma and chronic obstructive pulmonary disease (COPD).

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.
