4-Heptanone 2,4-dinitrophenyl hydrazone is a chemical compound derived from 4-heptanone, an organic ketone with the molecular formula C7H14O. The compound is formed by the reaction of 4-heptanone with 2,4-dinitrophenylhydrazine, resulting in the formation of a hydrazone derivative. This yellow crystalline solid is used as a reagent in organic synthesis and as a derivatizing agent for the detection and identification of ketones in analytical chemistry. The compound has a molecular weight of 241.26 g/mol and is characterized by its melting point of 85-87°C. It is soluble in common organic solvents such as ethanol, acetone, and dichloromethane. Due to the presence of nitro groups, 4-heptanone 2,4-dinitrophenyl hydrazone is sensitive to light and heat, and should be stored in a cool, dark place to maintain its stability.

Check Digit Verification of cas no

The CAS Registry Mumber 1655-41-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1655-41:
(6*1)+(5*6)+(4*5)+(3*5)+(2*4)+(1*1)=80
80 % 10 = 0
So 1655-41-0 is a valid CAS Registry Number.

Kinetics and mechanism of oxidation of aliphatic secondary alcohols by benzyltrimethylammonium chlorobromate

Sharma, Pradeep K.

, p. 2702 - 2706 (2014/06/09)

Oxidation of several secondary alcohols by benzyltrimethylammonium chlorobromate (BTMACB) in aqueous acetic acid leads to the formation of corresponding ketones. The reaction is first order with respect to BTMACB and the alcohols. The reaction failed to induce the polymerization of acrylonitrile. There is no effect of tetrabutylammonium chloride on the reaction rate. The proposed reactive oxidizing species is chlorobromate ion. The oxidation of benzhydrol-α-d (PhCDOHPh) exhibited a substantial primary kinetic isotope effect (kH/kD = 5.61 at 298 K). The effect of solvent composition indicated that the rate increases with an increase in the polarity of the solvent. The reaction is susceptible to both the polar and steric effects of the substituents. A mechanism involving transfer of a hydride ion in the ratedetermining step has been proposed.
