| Analysis Note: | These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available. |
| Application: | Caffeine may be used as a reference standard for the determination of the analyte in pharmaceutical formulations by high-performance liquid chromatography and spectrophotometry. |
| 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. |
| Biochem/physiol Actions: | A central nervous system stimulant believed to act through adenosine receptors and monoamine neurotransmitters. It is an adenosine receptor antagonist and adenosine 3′,5′-cyclic monophosphate (cAMP) phosphodiesterase inhibitor. Thus, levels of cAMP increase in cells following treatment with caffeine. It has been reported to affect cellular calcium levels, releasing calcium from intracellular stores. It overrides the cell cycle effects of various chemicals such as protease inhibitors, preventing apoptosis; and it has been shown to inhibit cellular DNA repair mechanisms. |

| 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. Caffeine is mainly used as a diuretic and as a stimulant to central nervous system, heart rate, and respiration. |
| 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. |
