S-Ibuprofen Extraction and Quantification

Check if the same lab product or an alternative is used in the 5 most similar protocols
A stock solution (2,000 mg L−1) of S-ibuprofen (Sigma-Aldrich, St. Louis, MO, USA) was prepared in methanol (Fisher Scientific, Fair Lawn, NY, USA) and stored at 4°C. Working solutions were prepared by dilution of the stock standard solution. Chloroform (Sigma-Aldrich) was used as an extractant solvent and methanol was used as a dispersant. A stock cobalt (Co(II)) solution (10 % (w v−1)) was prepared by dissolving CoCl2·6H2O (Sigma-Aldrich) in water and stored at 4°C. Working solutions was obtained by diluting the stock cobalt solution. Diluted sodium hydroxide solution, prepared from solid NaOH pellets (Fisher Scientific), was used for pH adjustment. Sodium chloride was purchased from Sigma-Aldrich. D-glucose was purchased from Merck (Darmstadt, Germany), while MgCl2·6H2O was purchased from Sigma-Aldrich.

Methanol, ammonium acetate, acetic acid and ammonium formate were HPLC grade and obtained from Sigma Aldrich. The reference materials R/S(±)-naproxen, R(-)-naproxen, S(+)-naproxen, R/S(±)ibuprofen, R(-)-ibuprofen, S(+)-ibuprofen, R/S(±)-salbutamol, R/S(±)-bisoprolol, R/S(±)-metoprolol, R/S(±)-amphetamine, S(+)-amphetamine, R(-)-amphetamine, R/S(±)-propranolol, R/S(±)-acebutolol, R/S(±)-fluoxetine, R/S(±)-atenolol, R(+)-atenolol, S(-)-atenolol R/S(±)-chlorpheniramine, and R/S(±)citalopram were purchased from Sigma Aldrich (Gillingham, UK) and Toronto Research Chemicals (Toronto, Canada). The corresponding deuterated surrogates were also purchased as racemates: R/S(±)-
atenolol-d7, R/S(±)-chlorpheniramine-d6, and R/S(±)-citalopram-d6. All chemicals were purchased as Methanolic solutions of 0.1 mg mL -1 or 1 mg mL -1 , or as powder. Powders were prepared at an appropriate concentration in Methanol. All solutions were stored in the dark at -20°C. Oasis HLB cartridges (3cc 60mg) were purchased from Waters (Manchester, UK).

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.
