Caffeine d9

Manufactured by CDN Isotopes

Sourced in Canada

Caffeine-D9 is a stable isotope-labeled compound used as an analytical standard in various research and development applications. It contains nine deuterium atoms, which replace the hydrogen atoms in the caffeine molecule. Caffeine-D9 is commonly used as an internal standard in the quantitative analysis of caffeine in biological samples, such as blood, urine, and food products.

Ultra-pure water was generated employing a Milli-Q Integral Water Purification System from Merck Millipore (Darmstadt, Germany). LC–MS grade solvents (CH₃CN, isopropanol (IPA), and CH₃OH) were acquired from Scharlau (Barcelona, Spain). Formic acid (≥ 95%), and ammonium acetate (≥ 98%) were purchased from Sigma-Aldrich Química SL (Madrid, Spain). Internal standards (ISs) phenylalanine-D₅, tryptophan-D₃ and caffeine-D₉ were purchased from CDN Isotopes (Pointe-Claire, Canada). Valproic acid (VPA) (> 98%), acetaminophen (APAP) (> 99%) and citric acid (CA) (> 99%) were obtained from Sigma-Aldrich (San Luis, MI, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
