All chemicals for the syntheses were purchased from commercial sources (Aldrich, Acros or Alfa Aesar) and used as received without further purification. N-Ethylglycine-hydrochloride (H₂EtGlyCl) and N-propylglycine-hydrochloride (H₂PrGlyCl) were prepared by aminolysis of chloroacetic acid according to the method of E. Fischer (Scheme S1†).^{40 (link)} CHN analyses were performed on a Perkin-Elmer 2400 Series II CHNS analyzer in the Analytical Services Laboratory at the Ruđer Bošković Institute, Zagreb, Croatia. The IR spectra were obtained in the range 4000–450 cm⁻¹ on a Perkin-Elmer Spectrum Two™ FTIR-spectrometer in ATR mode. The TGA measurements were performed at a heating rate of 10 °C min⁻¹ in the temperature range 25–600 °C, under a nitrogen flow of 150 mL min⁻¹ on a Mettler-Toledo TG/SDTA 851^e instrument. Approximately 10 mg of each sample was placed in a standard aluminum crucible (40 μL).
ESR measurements were conducted on a Bruker Elexsys 580 FT/CW spectrometer. The used microwave frequency was around 9.7 GHz; the magnetic field modulation amplitude was 0.5 mT and the modulation frequency was 100 kHz. Samples were studied in the range from room down to liquid helium temperature.

Synthetic Procedures and Characterization

Check if the same lab product or an alternative is used in the 5 most similar protocols

All
commercially available chemicals were purchased from Aldrich, USA
or Spectrochem, India and used without further purification. All solvents
were used as received. The progress of the reaction was checked by
glass sheet precoated TLC with silica gel (with binder, 300 mesh,
Spectrochem), and column chromatography was performed using silica
gel (100–200 mesh). Bruker 300 and 400 MHz instruments were
used for obtaining ¹H and ¹³C NMR spectra at
300, 400, 75, and 100 MHz, respectively. Chemical shifts are reported
in parts per million (ppm) downfield from an internal TMS (tetramethylsilane)
reference. Coupling constants (J) are reported in
hertz (Hz), and spin multiplicities are represented by the symbols
s (singlet), brs (broad singlet), d (doublet), t (triplet), q (quartet),
and m (multiplet). HRMS with an ESI resource were acquired using a
Waters XEVO-G2S Q TOF mass spectrometer. A 2400 Series II CHNS Analyzer,
Perkin Elmer USA was used for elemental analyses. Melting points were
recorded with an open capillary on an electrical melting point apparatus,
and the single-crystal structures of the synthesized compounds were
confirmed by an X-ray crystallography experiment on a Bruker SMART
diffractometer.

The thermal stability and decomposition of 2-HPAA and its alkali metal salts were examined using a STA 600 Simultaneous Thermal Analyzer/FTIR Frontier (PerkinElmer, Waltham, MA, USA). The samples (5–6 mg) were heated in a ceramic crucible in the range 30–995 °C in flowing air atmosphere with a heating rate of 10 °C/min. The products of dehydration and decomposition processes were established on the basis of the TG, DSC, and DTG curves. The elemental analysis was conducted with the Perkin–Elmer 2400 Series II CHNS Analyzer.

All commercially available chemicals of reagent grade were used as received without further purification. The CHN-microanalysis was carried out on a PerkinElmer 2400 Series II CHNS analyzer in the Analytical Services Laboratory at the Ruđer Bošković Institute, Zagreb. The FT-IR spectra were measured on a PerkinElmer Spectrum Two spectrometer in the spectral range 4000–450 cm⁻¹ as KBr pellets. NMR spectra were recorded on an NMR spectrometer Bruker Avance III HD 400 mHz/54 mm Ascend in DMSO as solvent. Powder X-ray diffraction (PXRD) was performed on a Malvern Panalytical Aeris diffractometer in the Bragg-Brentano geometry with CuK_α radiation (λ = 1.54184 Å) at room temperature. The samples were placed on a silicon holder and the diffractograms were measured in the 2θ range 5–40° with a step size of 0.022° and 15.0 s per step. Powder X-ray diffraction data were collected and visualized using the HighScore Plus program [26 ].

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.
