Provide a procedure for purifying a desired organic compound by removing an undesired impurity, using technique of extraction. You will be using a microscale (100mg solute mixture in 2mL organic solvent). You can assume that the organic solvent is whatever immiscible solvent you choose. The choice is not critical, but choosing a solvent based on density could simplify your extraction procedure. For reagents, you can assume that you have the following at your disposal: • 5% aqueous HCI • 5% aqueous NaOH • saturated sodium bicarbonate • saturated sodium carbonate • saturated aqueous sodium chloride • sodium sulfate • extra immiscible organic solvent of your choice (e.g. if your initial mixture is dissolved in diethyl ether, extra diethyl ether will be available) Any laboratory glassware and equipment needed for the procedure (e.g. separatory funnel; rotary evaporator) would be available as well. desired compound undesired impurity HO

Solution Calculations Using unit analysis, clearly show the set-ups for your calculations. You wish to prepare 50.0 mL of 2.30 x 10–2 M solution of Levothyroxine (hint-how many grams will you need of Levothyroxine?) 1. Describe how to prepare this solution from the pure drug and deionized water. Analytical balances and volumetric flasks are available to you. (Assume that Levothyroxine dissolves in water, at least to the extent necessary for this problem.) Use complete sentences in your description of the solution preparation process. a. A patient is given 2.0mL of a 3.00% (m/v) solution of Levothyroxine, how many milligrams of the drug did they receive? b. What is the molarity of a 3.00% (m/v) solution of Levothyroxine?

As a newly appointed research officer, Marissa has been assigned a task to separate a mixture containing acetone, acetamide and 1,2-dichloroethane using a high-performance liquid chromatography (HPLC) technique. The instrument was equipped with a 40-cm column packed with cyano propyl bonded to the siloxane backbone material. i) List THREE (3) examples of mobile phase solvent/solvent systems that can be used with the column above. ii) Determine the sequence in which the three analytes eluted from the column and explain the underlying principle applied. iii) Sketch the chromatogram that would be produced if the column was replaced with a column filled with C18 hydrocarbon bound to the siloxane backbone material and acetonitrile was employed as the mobile phase. Label the peaks observed.

Describe and explain the effect(s) on your result for the following possible experimental errors. In each case, specify the component(s) whose percentage(s) would be too high or too low and explain your rationale why these would be changed. (a) After adding DCM to the counterfeit pharmaceutical at the beginning, you didn’t stir or shake the mixture before filtering. (b) Washing the sucrose recovered during the first vacuum filtration with water rather than DCM. (c) During the NaHCO3 extraction, you failed to mix the organic and aqueous layers thoroughly. - B (d) You mistakenly extracted the DCM solution with 5% HCl rather than 5% NaHCO3. (e) You neutralised the NaHCO3 solution to pH7 rather than pH2.
