193280-15-8 Usage
General Description
1,3-Cyclopentanedicarbonyl difluoride, 1,2,2-trimethyl-, (1R-cis)- (9CI) is a chemical compound that is also known as menthyl glyoxylate. It is a fluorinated derivative of menthone, which is commonly used in the production of pharmaceuticals, insecticides, and other agricultural chemicals. Menthyl glyoxylate is a colorless liquid with a strong odor and is highly reactive. It is commonly used as a reagent in organic synthesis, particularly in the production of chiral compounds. 1,3-Cyclopentanedicarbonyl difluoride, 1,2,2-trimethyl-, (1R-cis)- (9CI) is also used in the creation of perfumes and fragrances due to its strong and characteristic odor. Additionally, it is also utilized in the manufacturing of flavors and as a chemical intermediate in various industrial processes.
Check Digit Verification of cas no
The CAS Registry Mumber 193280-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,2,8 and 0 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 193280-15:
(8*1)+(7*9)+(6*3)+(5*2)+(4*8)+(3*0)+(2*1)+(1*5)=138
138 % 10 = 8
So 193280-15-8 is a valid CAS Registry Number.

Selective fluorination of (1R,3S)-(+)-camphoric acid with sulphur tetrafluoride. Preparation of fluorinated optically active derivatives of 1,2,2-trimethylcyclopentane
Dmowski, Wojciech,Kozlowski, Tomasz
, p. 187 - 190 (2007/10/03)
Treatment of (1R,3S)-(+)-camphoric acid (1) with sulphur tetrafluoride at ambient temperature gives, in general, three products: 1,2,2-trimethyl-3-trifluoromethyl-1-cyclopentanoyl fluoride (2), 2,2,4,4-tetrafluoro-1,8,8-trimethyl-3-oxa-bicyclo[3.2.1]octane (3) and camphoroyl difluoride (4). The ratio of products strongly depends on the reaction time. Alkaline hydrolysis of (2) gives 1,2,2-trimethyl-3-trifluoromethyl-1-cyclopentanecarboxylic acid (5), quantitatively. All products exhibit optical activity.
