Usage

Uses

7-Oxooctanoic acid was employed as test compound to investigate the applicability of high-resolution electrospray ionization mass spectrometry to the measurements of average oxygen to carbon ratio (O/C) in secondary organic aerosols. It may be used in the synthesis of hapten, which was used to obtain antibody for the detection of triacetone triperoxide (an improvised explosive). It may be used in the synthesis of “queen substance” of the honey bee.

General Description

7-Oxooctanoic acid is fatty acid formed by the action of acid synthases from acetyl-CoA and malonyl-CoA precursors.

Selective C-C Bond Cleavage of Cycloalkanones by NaNO2/HCl

A novel selective fragmentation of cycloalkanones by NaNO2/HCl has been established. The C-C bond cleavage reaction proceeds smoothly under mild conditions, selectively affording versatile keto acids or oxime acids. The methodology can streamline the synthesis of valuable chiral molecules and isocoumarins from readily available feedstocks.

Analytical methodology for determination of organic aerosol functional group distributions

Secondary organic aerosol (SOA) particles result from the condensation of oxidized volatile organic compounds (VOC) and consist of a complex mixture that is not conducive to complete compositional analysis. We present a simple methodology for determining the quantities of aldehydes and ketones, alcohols, and carboxylic acids in such samples via derivatization and high-performance liquid chromatography (HPLC) with ultraviolet-visible absorption detection and tandem mass spectrometry (MS/MS). Useful concentration ranges are presented with an examination of the specificity of these compounds in multiply substituted systems. Such data are valuable in modeling the formation of laboratory-generated aerosols and in identifying point sources of field-collected aerosol samples. Calibration curves on standard samples, MS/MS transitions, including collisionally induced dissociation (CID) products, and a quantitative examination of the specificity of the derivatization reagents toward multiple functional groups are presented for a series of aliphatic standard samples. These methods are then applied to filter extracts from SOA derived from 1-iodooctane photolysis at 254 nm to demonstrate the methodology on a complex system. Ultimately, this methodology enables the measurement of variations in the chemical nature of the oxygen within an SOA particle, providing a distribution of functional group concentrations.
