Raju Chandra et al; A reliable and reproducible reversed-phase high performance liquid chromatography (RP-HPLC) was developed for the quantitative determination of quetiapine fumarate from marketed bulk tablets. The active ingredient of quetiapine fumarate separation achieved with C18 column using the methanol water mobile phase in the ratio of 30:70 (v/v). The active ingredient of the drug content quantify with UV detector at 359 nm. The retention time of quetiapine fumarate is 5.27 min. A good…

Rhapsody at Chimbiya (Drama) Breaks squeaked and the engine boomed announcing its arrival at Chimbiya bar. Suspicious four faces alighted from the machine without number plates and entered the bar. “Barman, give us four beers,” one of the four men with a scar above his right eye and slightly shorter shouted. Make sure the beers are cold added another of the group After an hour, the bar was full of patrons. Call me, Bonzo; the man with the scar told the bartender. And that man with a…

In “Raisin in the Sun” Walter's character is held back from achieving his dreams because of obstacles that stand in his way. Walter's dreams dramatically change from the beginning to the end of the book. For example, at the beginning of the book the majority of his dream is to own a liquor store, and by the end he only wants to help his family. However, many people stand in his way of achieve his dream. At the start of the book when Walter is fighting for his dream of a owning liquor store, he…

Results and Discussion Synthesis of Tin(IV) Porphyrin-Viologen Dyad: Tin(IV)porphyrin-viologen dyads 1 & 2 (scheme 1) used in this study was synthesized by a series of reactions. 1-(4-Carboxybenzyl)-1'-methyl-4,4'-bipyridinium hexaflurophosphate was prepared from the reaction between 1-Methyl-4,4'-bipyridinium iodide with 4-(bromomethyl)benzoic acid followed by ion exchange with NH4PF6. Reaction of 1-(4-Carboxybenzyl)-1'-methyl-4,4'-bipyridinium hexaflurophosphate with [Sn(OH)2TPP] (TPP =…

4.3 High Performance Liquid Chromatography (HPLC) An HPLC analysis was carried out for the Fraction C2-7 for confirmation of the results obtained by TLC analysis. According to the HPLC chromatogram, there is only one peak was observed at the retention time of 4.510 minutes. Therefore, it can be concluded that there is only one compound presents in the Fraction C2-7. Basically, the first few small peaks in the chromatogram which is around 2-3 minutes are ‘noise’ from the injection that been made…

Green Chemistry and the Diels-Alder Reaction Purpose The purpose of this reaction is to bring about the movement of green chemistry which is a safer, more sustainable chemistry to all levels of chemistry. The use of 12 principles can make in principle a reaction greener with the use of modifications. In this lab, the Diels-Alder reaction will be performed by reacting (E,E)-2,4-hexadien-1-ol with maleic anhydride without the use of a solvent to make the reaction more greener. The reaction will…

Summary of Abstinence I tried to give up soda for six weeks for my abstinence project. For the first two weeks, I stayed strong and did not have any soda. Every time I would usually have a soda, I replaced it with water. At the beginning of my third week, I relapsed and drank soda. The reason I had soda was because my stomach was upset and I am use to drinking ginger ale when this occurs. From there, I went through a downward spiral, and continued to drink soda. I tried not to drink soda as…

Solventless Reactions: The Aldol Reaction CH204-01 Fadwa Mekkaoui Introduction: An aldol reaction is the formation of a new carbon-carbon bond by the addition of a nucleophile to an electron deficient carbon. The reaction is favorable in Green Chemistry. It demonstrates green principles such as using no solvent and having a high atom economy. In the lab a mixed aldol reaction was performed to synthesize an unsaturated ketone from and aldehyde and ketone. By using an aldehyde, that doesn’t…

When examining the the location of the vehicle and how it arrived there, courts generally view a vehicle being found in a parking lot of the original location more favorably than on or near busy streets. In Hiegel v. State and Nichols v. State, the location of the vehicles were found in the original location where the drinking occurred. (Cite) Both cases the vehicles were found off the road in a area that did not increase the risk of harm to public or themselves, such as a tavern parking lot.…

This thesis mainly focused on analysis approaches of twenty potential isomeric and designer drugs of 1-pentylacylindoles series of synthetic cannabinoids compounds associated mainly with naphthoylindoles and benzoylindoles structures, via using various analytical methods. These isomers and analogs represent potential designer modification of banned drugs and show the same elemental composition and yielding identical nominal, exact masses and general analytical properties which make the potential…
