    Fentanyl According to Susan Robertson, the drug fentanyl which is an opiate agonist, has been around since the 1960s and created by Dr. Paul Jansen. "The use of fentanyl as a pain reliever and anesthetic was quickly adopted in the medical setting. In the 1960s, the agent was introduced as an intravenous anesthetic under the brand name Sublimaze"(S.Robertson)pg.1. In the 90s fentanyl was turned into a patch which breaks down into the blood stream through a period of 72 hours.…

    Methadone is a Schedule II drug that belongs to the opioid family of drugs. Methadone it is an extended acting synthetic tranquilizing painkiller. In the early 1960s, two New York physicians, Marie Nyswander and Vincent Dole, ascertained that when methadone is taken on a daily base, it is a constructive habituated medical treatment for individuals who have become opioid addicts. Since the 1960s, methadone has been strategized to help people who are dependent on illicit drugs such as opioid, heroin, morphine, and codeine.…

    4-Aminoacetophenone Synthesis Lab Report

    Purpose The purpose of this lab was to separate unknown compound 204, composed of an amine, a carboxylic acid, and a neutral component, into each of its three respective states. The unknown compound was separated using microscale separation of acidic, basic, and neutral components by liquid/liquid extraction. Liquid/liquid extraction is a very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in separating reactants and products of a synthesis. The components were purified and dried by evaporation and vacuum filtration.…

    According to Webster Dictionary, ecstasy is defined as “an illegal drug that is used to produce a feeling of excitement and pleasure” Ecstasy. (n.d.). Retrieved November 11, 2016, from http://www.merriam-webster.com/dictionary/ecstasy. As with all drugs, ecstasy was produced to treat one symptom and evolved to affect another part of the brain. This research will address: what is ecstasy, how does ecstasy work, the short and long-term effects from using ecstasy, users of the drug, and prevention and support. Although ecstasy was introduced as a legal drug to address an ailment, its long term effects caused it to not be an efficient drug for consumption and an illegal drug.…

    Acid-Catalyzed Hydration Report

    The actual weight of the ester was 0.6 g, producing a percent yield of 30.3%, meaning that the efficiency of the reaction was accurate because percent yield was less than 100%. Anything greater than 100% means that something went wrong in the experiment. The experimented melting point was 104.2℃, which was less than the expected melting point at 124-126℃ (ChemSpider). This was most likely due to the impurities being present in the sample, and some moisture still being present in the recovered caffeine when the melting point was determined.…

    Limiting Reactant In A Chemical Equation

    Whichever reactant results in the smallest amount for the product is the limiting reactant, and the number itself is the theoretical yield. The theoretical yield is the maximum amount produced from a balanced chemical equation based on 100% efficiency. The actual yield is the amount that is actually produced in lab. To find the percent yield, divide the actual yield by the theoretical yield and multiply that by one hundred. In this lab we will use the steps listed above to find the mass of the precipitate is formed from a double replacement chemical reaction.…

    P Toluidine Synthesis Analysis

    Benzocaine was synthesized from p-toluidine in a four step synthesis. Each intermediate product, including N-acetyl-p-toluidine, p-acetamidobenzoic acid, and p-aminobenzoic acid, was checked for yield, presence, and purity through weighing, taking IR and NMR spectrums, and determining the melting point. Thin Layer Chromatography was used to ensure the completion of the final reaction from p-aminobenzoic acid to benzocaine. The yield of the first step from p-toluidine to N-acetyl-p-toluidine was 91.9%. The yield of the second step from N-acetyl-p-toluidine to p-acetamidobenzoic acid was 49.85% The yield of the third step from p-acetamidobenzoic acid to p-aminobenzoic acid was 32.49%, which was not enough to continue so some product was borrowed…
