Abstract:
The decomposed body of a 45-year-old female was found, face down, in a mobile home, along with a suicide note and two antifreeze containers. Analysis of the body fluid collected from the decedent showed the presence of 58 mg/dL ethanol, but suspected ethylene glycol was not found in the sample. However, an unusually large peak of internal standard, 1,3-propanediol, was found in the sample. Gas chromatography-mass spectrometry analysis confirmed the presence of 1,3-propanediol in the sample. Using gas chromatography-flame-ionization detection, the concentration of 1,3-propanediol was determined to be 445 mg/dL. To our knowledge, this is the first report involving 1,3-propanediol as the cause of death. The study also highlights the importance for the close scrutiny of data, as 1,3-propanediol is a frequently used internal standard for the assay of glycols.

Protection
It defines a protecting group as the masking agent to make the more reactive species inert to a given set of conditions. This concept is depicted via the illustration of liquid flow through different outlets in an assembly of pipes. The analogy helps to understand the role...

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and phenols...
