1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC), NaCl, NaBr, NaI, benzylamine, 33 wt% methylamine in absolute ethanol, 66.0–72.0% ethylamine in H₂O, 3-(Dimethylamino)-1-propylamine, latex beads (polystyrene, 0.1 µm mean particle size), 4-morpholineethanesulfonic acid (MES) buffer were all purchased from Sigma–Aldrich. The precursor N-Boc-L-aspartic acid 1 and N-Boc-L-glutamic acid 3 were purchased from Alfa Aesar and TCI, respectively. All chemicals were used without any further purification. The precursor 2-hexen-1-yl-succinic acid 2 was synthesized by treating the corresponding anhydride with two (mass)-equivalents of MQ water, stirred overnight at room temperature, and then lyophilized^{41 (link)}. The product was stored at −20 °C until further use. The anhydride of N-Boc-L-aspartic acid was synthesized according to a previously published procedure, treating the diacid with the carbodiimide coupling agent DCC and recrystallization from an acetone/hexane mixture³⁰. HPLC grade acetonitrile was purchased from VWR. Milli-Q water was used provided from a Millipore water purifier system.

% D, Sigma Aldrich) were purchased and used as received. Before each
experiment, the fresh stock solutions of anhydrous CaCl₂ (10–30%) were prepared in deionized water. The final products
of VES molecules and the intermediates were characterized by ¹H-NMR and ¹³C-NMR on a 400 MHz Bruker spectrometer
(AVANCE III) using TMS as an internal solvent by dissolving samples
in deuterated solvents. The functional groups were ascertained by
an FT-IR spectrophotometer (Perkin Elmer 16F PC, Perkin Elmer Inc.
USA). The apparent viscosities of different VES formulations were
determined using a Brookfield Rheometer DV3T linked with thermosel
through a programmable temperature controller (Ametek, USA). Thermogravimetric
analysis (TGA) was performed to assess the thermal stability of the
final products using an SDT Q600 (V20.9 Build 20) thermal analyzer.

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.
