Reagents and solvents for the synthetic work were obtained from Sigma-Aldrich (St. Louis, MO, USA) and used as received. Viscoleo, Ph. Eur Grade medium chain triglyceride, C8/C10 (MCT) was purchased from Delios V (Illertissen, Germany), lecithin (E80) for the intravenous emulsion was obtained from Lipoid AG (Ludwigshafen, Germany) and glycerol from Sigma Aldrich (St. Louis, MO, USA). Hypergrade acetonitrile from Merck (Darmstadt, Germany) was used for the HPLC–MS/MS analysis, ethanol was from De Danske Spritfabrikker (Aalborg, Denmark) and deuterated aripiprazole used as the internal standard in the bioanalysis was purchased from Toronto Research Chemicals Inc. (Toronto, ON, Canada). Purified water was obtained from a Millipore Milli-Q Ultrapure Water purification system (Billerica, MA, USA). All other chemicals were of analytical grade or higher.

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.
