Quantitative Isotopic Analysis of Methyl Methacrylate

Check if the same lab product or an alternative is used in the 5 most similar protocols
2,3,4,5,6-Pentafluorobenzyl bromide (PFB-Br) was obtained from Sigma-Aldrich (Steinheim, Germany). Toluene was purchased from Baker (Deventer, The Netherlands). Acetone, Hünig base, d0-MMA, and d3-MMA (isotopic purity, 98% 2H) were supplied by Merck (Darmstadt, Germany). Stock solutions of d0-MMA and d3-MMA were prepared by dissolving accurately weighed amounts of the unlabeled and isotope-labeled MMA in deionized water. Stock solutions were diluted with deionized water as appropriate. Glassware for GC-MS (1.5-mL autosampler vials and 0.2-mL microvials) including the fused-silica capillary column Optima 17 (15 m × 0.25 mm I.D., 0.25 µm film thickness) were purchased from Macherey-Nagel (Düren, Germany).

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.
