Usage

General Description

NONANAL (DNPH DERIVATIVE) is a chemical compound derived from nonanal, which is an organic compound commonly found in essential oils and is used in the production of perfumes and flavoring agents. The DNPH derivative of nonanal is a chemical reagent commonly used in analytical chemistry to identify and quantify carbonyl compounds, such as aldehydes and ketones, in various samples. This derivative forms a colored complex with carbonyl compounds, making them easily detectable and measurable using analytical techniques such as spectrophotometry and chromatography. NONANAL (DNPH DERIVATIVE) is an important tool in the analysis of environmental pollutants, food additives, and industrial chemicals.

Formation of potentially toxic carbonyls during oxidation of triolein in the presence of alimentary antioxidants

Abstract: A relation between oil uptake and cancer as well as induction of hepatic inflammation was shown earlier. It is discussed that the main oil oxidation products—hydroperoxides and carbonyls—might be the reason for the mentioned diseases. In this manuscript quantitative determination of aldehydes which are formed during oxidation of triolein—as a model substance—using the Rancimat 679 is described. The oxidation of 11?g of triolein is carried out at 120?°C sparging air with a flow of 20?dm3/h for 10?h. A series of aliphatic aldehydes starting from hexanal to decanal as well as decenal was identified by LC–MS/MS and quantified as DNPH derivatives. In addition, the total amount of carbonyls was determined. Based on the calibration with hexanal, all other dominant substances were in the similar concentration range with maximum concentrations of 1.6?μmol/cm3 of hexanal, 2.3?μmol/cm3 of heptanal, 2.5?μmol/cm3 of octanal, 3.2?μmol/cm3 of nonanal, 4.0?μmol/cm3 of decanal after 6?h. The total amount of carbonyls reached a maximum after 6?h being 27?μmol/cm3 for triolein without antioxidant. The results of this investigation will be a basis for further toxicological studies on oxidized oils.

1-(Carbazol-9-ylmethyl)benzotriazole Anion: A Formyl Anion Equivalent

The title anion, readily available as its lithium derivative, smoothly reacts with a wide range of electrophiles to give well-characterized products which are easily hydrolyzed to the corresponding aldehydes in high overall yields.The method is compared with currently available routes.
