Menthol-β-d3 is a deuterated analog of menthol, a naturally occurring organic compound found in mint oils. It is a colorless to pale yellow liquid with a strong minty odor and taste. menthol-β-d3 is widely used in scientific research and chemical analysis as an internal standard for the quantification of menthol in various samples, such as pharmaceuticals, food products, and cosmetics. Menthol-β-d3 is particularly valuable in mass spectrometry and gas chromatography applications, as it helps to improve the accuracy and precision of menthol quantification by providing a stable isotope reference.

5113-63-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5113-63-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,1 and 3 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5113-63:
(6*5)+(5*1)+(4*1)+(3*3)+(2*6)+(1*3)=63
63 % 10 = 3
So 5113-63-3 is a valid CAS Registry Number.

Hydrogen Participation vs. Elimination. The Role and Fate of Neighboring Hydrogen in Solvolysis of Neomenthyl Tosylate

Hirsl-Starcevic, Sanja,Majerski, Zdenko,Sunko, Dionis E.

, p. 3388 - 3393 (2007/10/02)

Product composition and α-d1 and β-d3 isotope effects in the solvolysis of neomenthyl tosylate (8-OTs) were determined in 70 percent aqueous trifluoroethanol and 70 percent aqueous ethanol.Both trifluoroethanolysis and ethanolysis gave 1-2 percent neomenthol (97percent d3), 12-13percent cis-4-menthanol (100percent d3), 2-3percent trans-4-menthanol (100percent d3), 66-70percent 3-p-menthene (83percent d3 and 17percent d2), and 5-9percent 4,8-p-menthene (97percent d3), respectively.These results and the high value of the β-d3 isotope effect (kH/kD=2.45) were interpreted in terms of rate-determining hydride shift followed by elimination which accounts for 75percent of all products.In 85percent of the elimination productsthe migrating hydrogen (deuterium) is not the one being eliminated.
