7493-59-6 Usage
Chemical Properties
2,3-Undecadione has a strong, sweet cream, warm odor with a coconut oil note. It has a sweet cream and coconut milk taste.
Preparation
By reacting 3-bromo-2-undecanone with sodium azide in diluted methanol and then boiling the resulting solution with
concentrated HCl; also from methyl nonyl ketone via the monoxime of the title material.
Taste threshold values
Taste characteristics at 2.5 ppm: aldehydic, creamy, buttery and dairy-like with waxy, rancid and fat nuances.
Check Digit Verification of cas no
The CAS Registry Mumber 7493-59-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7493-59:
(6*7)+(5*4)+(4*9)+(3*3)+(2*5)+(1*9)=126
126 % 10 = 6
So 7493-59-6 is a valid CAS Registry Number.

In this communication we propose a convenient methodology to effect the oxidation of alkynes using ammonium persulfate and diphenyl diselenide as catalyst. The reactions effected in aqueous media lead to 1,2-unprotected dicarbonyl derivatives or to hemiacetals starting from terminal alkynes.
