were removed and the plate wells were washed with Phosphate buffered solution. Briefly‚ 50 IL of 2 mg/ml MTT and 150 IL culture medium were added to each well. The cells were incubated at 37 °C and 5% Co2 for 4 h. Then the media was discarded and dimethyl sulfoxide and Sorenson buffer was added to each well as solubilizer buffer. Finally‚ absorbance was read using an ELISA plate reader (BioTeck‚ Bad Friedrichshall‚ Germany) at 570 nm

Functional Groups of Organic Compounds A functional group is a specific arrangement of atoms in the HC derivative other than carbon and hydrogen. Literally‚ the functional group determines the functions of the particular HC derivative in chemical reactions. This means that the specific properties of the HC derivative are due to its functional group. Each functional group is attached to an alkyl radical (R). An alkyl radical is one H atom less than the given alkane. The alkyl radical (R) uses

2a: Infrared Spectroscopy and Analgesic Drug Identification Abstract: To be able to understand how organic soluble compounds could be isolated from non-organic components‚ a chromatographic separation process was used. The objective of the analgesic drug identification is to isolate the organic compounds/ active ingredients in an unknown drug. The identity of the drug was determined through melting point‚ percent recover‚ and Rf values. The comparable data for acetaminophen from the manufacturer

Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard
