6636-80-2 Usage
General Description
1-CYCLOPENTYL-PENTAN-1-ONE, also known as 1-cyclopentylpentan-1-one or 1-cyclopentylpentanone, is a cyclic ketone with the molecular formula C10H18O. It is a colorless liquid with a slightly sweet, floral odor. This chemical is used as a fragrance ingredient in perfumes and personal care products. It is also utilized as a flavoring agent in food products. Additionally, 1-CYCLOPENTYL-PENTAN-1-ONE is a versatile intermediate in the synthesis of various pharmaceuticals and other organic compounds. However, it is important to handle this chemical with care, as it can be harmful if ingested, inhaled, or it comes into contact with the skin. Proper safety precautions and handling procedures should be followed when working with this substance.
Check Digit Verification of cas no
The CAS Registry Mumber 6636-80-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6636-80:
(6*6)+(5*6)+(4*3)+(3*6)+(2*8)+(1*0)=112
112 % 10 = 2
So 6636-80-2 is a valid CAS Registry Number.

Continuous flow synthesis of ketones from carbon dioxide and organolithium or grignard reagents

We describe an efficient continuous flow synthesis of ketones from CO 2 and organolithium or Grignard reagents that exhibits significant advantages over conventional batch conditions in suppressing undesired symmetric ketone and tertiary alcohol byproducts. We observed an unprecedented solvent-dependence of the organolithium reactivity, the key factor in governing selectivity during the flow process. A facile, telescoped three-step-one-flow process for the preparation of ketones in a modular fashion through the in-line generation of organometallic reagents is also established.
