3,3,4-Trimethylpentan-2-one, also known as pivalic acid ketone or isopropylidene acetone, is an organic compound with the chemical formula C8H16O. It is a colorless, flammable liquid with a pungent odor. This ketone is a derivative of pentan-2-one, featuring three methyl groups attached to the third carbon atom. It is commonly used as a solvent, a reagent in organic synthesis, and a precursor in the production of various chemicals, including pharmaceuticals and fragrances. Due to its stability and low reactivity, 3,3,4-trimethylpentan-2-one is also employed as a protecting group in organic chemistry.

5340-47-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5340-47-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,4 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5340-47:
(6*5)+(5*3)+(4*4)+(3*0)+(2*4)+(1*7)=76
76 % 10 = 6
So 5340-47-6 is a valid CAS Registry Number.

ODORANT SECONDARY ALCOHOLS AND THEIR COMPOSITIONS

-

Page/Page column 35, (2019/12/25)

The present invention relates to new classes of odorous alcohols (odorants) derived from 2,3- dimethylbutene which are useful as fragrance or flavor materials in particular in providing natural piney olfactory notes with a complex profile to perfume, aroma or deodorizing/masking compositions.

Clocking Tertiary Cyclopropylcarbinyl Radical Rearrangements

Engel, Paul S.,He, Shu-Lin,Banks,Ingold,Lusztyk

, p. 1210 - 1214 (2007/10/03)

Three independent methods have been employed to estimate the rate constant, k1, for ring-opening of the 2-cyclopropyl-2-propyl radical, 1, at room temperature. These three estimates are based on chemical trapping of 1 and the ring-opened 4-methylpent-3-ene-1-yl radical by thiophenol (k1 = (1.65 ± 0.41) × 107 M-1 s-1), 9-azabicyclo[3.3.1]nonane-N-oxyl (k1 = (1.76 ± 0.34) × 107 M-1 s-1) and 2,2,6,6-tetramethylpiperidine-N-oxyl (k1 = (2.1 ± 0.4) × 107 M-1 s-1) and absolute rate constants for nonrearranging radicals structurally related to 1. The mean value for k1) ((1.84 ± 0.4) × 107 M-1 s-1) should be used when 1 is employed as a tertiary alkyl free radical clock at ambient temperatures.
