General Description
HEPTALDEHYDE (DNPH DERIVATIVE) is a chemical compound that is derived from the reaction of heptaldehyde with 2,4-dinitrophenylhydrazine (DNPH). It is used as a reagent in analytical chemistry for the detection and quantification of aldehydes and ketones. The DNPH derivative of heptaldehyde is used in various analytical techniques such as high-performance liquid chromatography (HPLC) and gas chromatography-mass spectrometry (GC-MS) to identify and measure the levels of aldehydes in environmental samples, food products, and industrial chemicals. This derivative is known for its high sensitivity and selectivity in detecting aldehydes, making it a valuable tool in chemical analysis and environmental monitoring. Additionally, it is important to handle heptaldehyde (DNPH derivative) with caution due to its potential hazards, including skin and eye irritation, and it should be used in a well-ventilated area with appropriate personal protective equipment.
Check Digit Verification of cas no
The CAS Registry Mumber 2074-05-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,7 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2074-05:
(6*2)+(5*0)+(4*7)+(3*4)+(2*0)+(1*5)=57
57 % 10 = 7
So 2074-05-7 is a valid CAS Registry Number.

Visible-light mediated C-C bond cleavage of 1,2-diols to carbonyls by cerium-photocatalysis

supporting information, p. 486 - 488 (2019/01/10)
We describe a photocatalytic method for the cleavage of vicinal diols to aldehydes and ketones. The reaction is catalyzed by blue light and a cerium-catalyst and the scope includes aryl as well as alkyl substituted diols. The simple protocol which works under air and at room temperature enables the valorization of abundant diols.
A novel synthetic method for the preparation of aliphatic aldehydes from the corresponding carboxylic acids

A novel synthetic method for the preparation of aliphatic aldehydes from the corresponding carboxylic acids via 1,3-dimethylbenzimidazolium salts is provided. 1,3-Dimethylbenzimidazolium salts were rapidly reduced with sodium/ethanol and then hydrolyzed with hydrochloric acid to obtain aliphatic aldehydes, in which the 1,3-dimethylbenzimidazolium salts can be readily achieved from the corresponding carboxylic acids. The mechanism for the reductive reaction of 1,3-dimethylbenzimidazolium salts with sodium/ethanol was discussed.
