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.

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.
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.

Analysis Note

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