Usage

General Description

Methacrolein-DNPH is a chemical compound derived from the reaction of methacrolein with 2,4-dinitrophenylhydrazine (DNPH). Methacrolein is a highly reactive compound commonly found in air pollution and industrial emissions. The derivative, methacrolein-DNPH, is often used as a standard for measuring and analyzing methacrolein levels in various environmental and industrial settings. It is also used in chemical research and quality control processes as a reference material for identification and quantification of methacrolein in gas and liquid samples. Methacrolein-DNPH is an important tool in environmental monitoring and industrial safety protocols for assessing and controlling exposure to harmful air pollutants.

Quantitative RP-HPLC determination of some aldehydes and hydroxyaldehydes as their 2,4-dinitrophenylhydrazone derivatives

A high-performance liquid chromatographic (HPLC) method is described for the quantitative determination of some aliphatic aldehydes and β- hydroxyaldehydes as their 2,4-dinitrophenylhydrazone derivatives. A method is described for the preparation of deriv

Synthesis of Analogues of 1,3-Dihydroxyacetone Phosphate and Glyceraldehyde 3-Phosphate for Use in Studies of Fructose-1,6-diphosphate Aldolase

This paper describes the synthesis of five analogues of dihydroxyacetone phosphate (3-azidohydroxyacetone 1-phosphate (5), 3-(acetylamino)hydroxyacetone 1-phosphate (12), (R)-1,3-dihydroxy-2-butanone 1-phosphate (18), (+/-)-1,3-dihydroxy-2-butanone 3-phosphate (26), and phosphonomethyl glycolate (31)).The syntheses of 18 and 26 are based on a new reaction: that is, the introduction of the phosphate group by the reaction of a diazo ketone with dibenzyl phosphate.These methods provide easy access to a number of compounds that are potential substrates for the synthetically useful enzyme aldolase (fructose-1,6-diphosphate aldolase from rabbit muscle, EC 4.1.2.13, RAMA) and perhaps for other enzymes of glycolysis.This paper also describes syntheses of 14 aldehydes for examination as substrates for aldolase.When the precursor was available, ozonolysis of vinyl groups proved to be the best route to the corresponding aldehydes.
