Advantages And Disadvantages Of Indole Pyrrole

3. The IR spectrum of the starting material shows a medium/strong C-O bond at around 1500cm-1, also the starting material shows a strong C-H bond at around 3000cm-1 and another medium C-H bond at 2865cm-1 indicating an aldehyde group whereas the product does not. The IR spectrum of the product shows a two weak broad O-H peaks at around

The product was placed in a Craig tube and several drops of hot (100°C) solvent (50% water, 50% methanol, by volume) was added and heated until all of the crystals dissolved. The Craig tube was plugged and set in an Erlenmeyer flask to cool. Crystallization was induced once the mixture was at room temperature by scratching the inner wall of the tube. It was then placed into an ice bath for ten minutes until crystallization was complete. The tube was then

1 Copper (II) Nitrate Crystals in vial, Copper Metal - 6-8 pc. in bag 2"x 3"

The product was then suspended in 2 ml of water with a stir rod in a 50 ml Erlenmeyer flask and heated to boiling. Water was added in one milliliter increments until all the product was dissolved (18 ml added total). The saturated solution was allowed to slowly cool, and gradual white crystal formation was observed. Recrystallized product was collected once more by suction filtration with the Hirsch funnel once crystallization ceased. Collected product dried on a watch glass for a week, weighed 0.14 g (1.2 mmol), and the melting point was 139°-141°

3.6.2. IAA (Indole 3 acetic acid) stock solution (10mM): 1.0mg of IAA being weighed and dissolved completely in acetone to a final total volume of 10 ml with autoclaved double distilled water to obtain a stock concentration of 10mM was prepared and stored in clean autoclaved vials at -4°C.

Fragment 7 is shown in the structure. Electron density map suggested two bulk electro-rich group present in the fragment, which corresponds to the two ring structure on 7. The heterocyclic ring has high e-density and forms a hydrophobic interaction with Leu144 residue. The e-rich NH2 group on this ring

The solution was let cool in ice water then using vacuum filtration to obtain the final product. Although the obtained product was white like powder, the identity of the product couldn’t be confirmed as cyclododecanone yet. Letting the obtained product stay open on the watch glass overnight to make sure all methanol evaporated. Following the third part was infrared spectroscopy and melting point to characterize the

The unknown NMR/IR Unknown #7 was C8H11N. The first in determining the structure from looking at the NMR spectra was to determine the degrees of saturation (DoU). DoU helps identify the number of bonds within the compound. The DoU can be determined by looking at the chemical formula and using the equation, DoU= (2C + 2 + N - X – H)/ (2). For this particular compound, I identified that the DoU was 4. Next, using the given IR peak, as well as looking at the chemical formula, the weak wavelength of 3400 cm-1 was identified as a amine function group, and that particular peak was a N-H bond stretch. Next the NMR spectra was examined. Using the spectra, I noticed there were four different peaks, The first peak was a singlet around 7.3-7.3 ppm and only had one hydrogen on the compound.

They can be worked for protection, divination; banishing, purification, evoking and sprinkling a small pinch of corresponding herbs into the candle flame can give more power to your spell.

Materials: Solutions of crystal violet and sodium hydroxide were available in the laboratory which were previously prepared of concentrations 2.00 E-5 and 2.00 E-2 respectively. Deionized water was used

It is commonly used as an antimicrobial. Currently, research is being done to determine the viability of using the molecule to prevent the spread of HIV and to destroy cancer cells.

To a 5 mL conical vial with a spin vane, 5-nitro-2, 3-dihydrophthalazine-1, 4-dione (.151 grams) was added. Next, sodium hydroxide (2 mL, 3M) was added to the conical vial and stirred until a reddish brown color was obtained. The addition of sodium hydrosulfite (.254 grams) followed, and the sides of the conical vial were

The week after, a recrystallization was performed on the previous week’s crude product. The product ethereal solution was first heated on a steam bath until dry. During the heating, a beaker of methanol was collected and also placed on the steam bath. Once the product was dry, it was cooled to room temperature and then placed in an ice-water bath. The now boiling methanol was added to the crude crystals and a recrystallization was performed. Once completed, the now purified product was collected via Buchner vacuum filtration and stored in drawer to dry for a week. Afterwards, a melting point range of the purified product was obtained by using a Mel-temp apparatus. Lastly, an

The light yellow precipitate was collected by suction filtration using a Hirsch funnel. The product was washed with two 1-mL portions of cold methanol followed by two 1-mL portions of diethyl ether. The product was dried in the oven at 110°C. The IR spectrum as a KBr pellet was obtained for the product and inosine for analysis.

To characterize the synthesized product using its boiling point, results of simple chemical tests and derivatization reactions, along with the determination of the melting points of the hydrazones and comparison of the hydrazones using their RGB values.
