13019-20-0 Usage
Chemical Properties
Colorless clear liquid
Occurrence
Reportedly present in Muscadine grapes (Vitis rotundifolia), cooked chicken and wine (white and rose).
Uses
2-Methyl-3-heptanone was used as an internal standard in dynamic headspace sampling, direct solvent extraction and vacuum simultaneous steam distillation–solvent extraction for sample preparation in volatile compound analysis in Thai soy sauce. It was used as an internal standard in the identification of volatile flavor compounds of stored nonfat dry milk using gas chromatography-olfactometry and aroma extract dilution analysis.

General Description
2-Methyl-3-heptanone is a colorless to light yellow liquid. It is one of the trace taste- and odor-causing organic compounds present in natural water.
Check Digit Verification of cas no
The CAS Registry Mumber 13019-20-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,0,1 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13019-20:
(7*1)+(6*3)+(5*0)+(4*1)+(3*9)+(2*2)+(1*0)=60
60 % 10 = 0
So 13019-20-0 is a valid CAS Registry Number.

A VERSATILE ACCESS TO UNSYMMETRICAL AND SYMMETRICAL α-DIKETONES VIA ORGANOTIN REAGENTS
Verlhac, Jean-Baptiste,Chanson, Evelyne,Jousseaume, Bernard,Quintard, Jean-Paul
, p. 6075 - 6078 (2007/10/02)
Unsymmetrical α-diketones have been obtained via cross coupling of acyltins with acyl halides under PdCl2(PPh3)2 catalysis while symmetrical α-diketones have been readily obtained via "in situ" formation of acyltins using hexabutylditin and acyl chlorides under similar experimental conditions.
