2-methyl-1-pentanal 2,4-dinitrophenylhydrazone is a chemical compound derived from the reaction of 2-methyl-1-pentanal, an aldehyde, with 2,4-dinitrophenylhydrazine, a reagent used in the formation of hydrazones. 2-methyl-1-pentanal 2,4-dinitrophenylhydrazone is characterized by its molecular formula C12H18N4O4, and it exhibits a molecular weight of 278.29 g/mol. It is a yellow crystalline solid, often used in analytical chemistry for the detection and identification of aldehydes. The formation of the hydrazone derivative from 2-methyl-1-pentanal involves the reaction of the aldehyde's carbonyl group with the hydrazine, resulting in a stable, easily identifiable product that can be analyzed through various techniques such as thin-layer chromatography or melting point determination. 2-methyl-1-pentanal 2,4-dinitrophenylhydrazone is an example of how functional group chemistry can be used to create derivatives that facilitate the study and detection of specific molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 1884-73-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,8 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1884-73:
(6*1)+(5*8)+(4*8)+(3*4)+(2*7)+(1*3)=107
107 % 10 = 7
So 1884-73-7 is a valid CAS Registry Number.

Copper(I)/ABNO-catalyzed aerobic alcohol oxidation: Alleviating steric and electronic constraints of Cu/TEMPO catalyst systems

Steves, Janelle E.,Stahl, Shannon S.

, p. 15742 - 15745 (2013)

Cu/TEMPO catalyst systems promote efficient aerobic oxidation of sterically unhindered primary alcohols and electronically activated substrates, but they show reduced reactivity with aliphatic and secondary alcohols. Here, we report a catalyst system, consisting of (MeObpy)CuI(OTf) and ABNO (MeObpy =4,4′-dimethoxy-2,2′-bipyridine; ABNO = 9-azabicyclo[3.3.1]nonane N-oxyl), that mediates aerobic oxidation of all classes of alcohols, including primary and secondary allylic, benzylic, and aliphatic alcohols with nearly equal efficiency. The catalyst exhibits broad functional group compatibility, and most reactions are complete within 1 h at room temperature using ambient air as the source of oxidant.
