Castor oil (B.P. grade) was purchased from a local pharmacy (Dischem, Cape Town, South Africa). Isobornyl methacrylate (IBOMA, technical grade, stabilized with 150 ppm monomethyl ether hydroquinone), styrene (≥99%, stabilized with 4-tert-butylcatechol), glycerol (98%), Ca(OH)2 (≥95%), maleic anhydride (MA, 99%), sodium hydrogen carbonate (NaHCO3, 99.7%), sodium hydroxide (99.5%), hydroquinone (98%), N,N-dimethylaniline (N,N-DMA, ≥99%), N,N-dimethylbenzylamine (N,N-DMBA, ≥99%), dibenzoyl peroxide (BPO, Luperox A75), surfactant (Ewopal 80), diethyl ether (99%), toluene (99.5%) were purchased from Sigma Aldrich (Modderfontein, South Africa). Oxalic acid, sodium hydroxide, ethanol (99.6%), and anhydrous MgSO4 were supplied by Kimix Chemicals, Cape Town, South Africa. styrene contained 4-tert-butylcatechol stabilizer, which was removed by washing with 2M NaOH twice, followed by sequential washing with distilled water and a 4 wt% NaCl aqueous solution. The product was then dried over anhydrous MgSO4 and filtered. All other materials were used as received.
N n dimethylbenzylamine
Manufactured by Merck Group
Sourced in United States
N,N-dimethylbenzylamine is a chemical compound that is commonly used as a reagent in organic synthesis and as a precursor in the production of various pharmaceutical and agrochemical products. It is a colorless to pale yellow liquid with a characteristic odor. The core function of N,N-dimethylbenzylamine is to serve as a building block for the synthesis of other organic compounds.

Ferrocene, thiophene, N,N′-dimethyl benzyl amine (BDMA), and methyl tetrahydrophthalic anhydride (MeTHPA) were purchased from Sigma Aldrich (St. Louis, MO, USA). Acetone was purchased from Samchun Chemical (Seoul, Korea). Bisphenol A diglycidyl ether (DGEBA) and diethyltoluenediamine (DETDA) were provided by Kukdo Chemical (Seoul, Korea). All the chemicals were used without further purification.

For preparation of the ESI and SESI buffer solution, water (H2O, Optima, Fisher Chemical, LC/MS grade), methanol (MeOH, Optima, Fisher Chemical, LC/MS grade) and formic acid (FA, Merck, for analysis, purity 98–100%) were used. As model compounds, six readily available isobars, which are separable in MS1 but co‐fragment in MS2, were selected and are shown in Figure 2 . Namely, benzothiazole (1 , TCI, purity >96.0%), pyridine‐2,6‐dicarbaldehyde (2 , Fluorochem, purity ≥98%), 3H‐pyrrolo[2,3‐d]pyrimidin‐4(7H)‐one (3 , Fluorochem, purity ≥95%), adenine (4 , Sigma‐Aldrich, purity ≥99%), acetanilide (5 , Sigma‐Aldrich, purity ≥99.5%) and N,N‐dimethylbenzylamine (6 , Sigma‐Aldrich, purity ≥99%) were used. For an exemplary application, azelaic acid (7 , Sigma‐Aldrich, purity ≥98%) and 10‐hydroxydecanoic acid (8 , Apollo Scientific, purity ≥95%), which were previously identified in a breath metabolomic study,38 were used for control measurements. Commercial calibration solutions (Pierce ESI Positive Ion Calibration Solution and Pierce ESI Negative Ion Calibration Solution, Thermo Scientific) were used to mass calibrate the instrument with the ESI source.
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.
