Cis-2-butylcyclopropanecarboxylic acid ethyl ester is an organic compound with the molecular formula C9H16O2. It is a derivative of cyclopropane, a three-membered cyclic hydrocarbon, with a butyl group attached to the second carbon atom. The carboxylic acid group is present at the second carbon atom as well, and it is esterified with an ethyl group, forming an ester linkage. cis-2-butylcyclopropanecarboxylic acid ethyl ester is characterized by its unique cyclic structure and the presence of a butyl chain, which influences its physical and chemical properties. It is an oily liquid with a distinct aroma and is used in the synthesis of various pharmaceuticals and fragrances due to its reactive functional groups and potential for further chemical modification.

Check Digit Verification of cas no

The CAS Registry Mumber 5532-44-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,3 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5532-44:
(6*5)+(5*5)+(4*3)+(3*2)+(2*4)+(1*4)=85
85 % 10 = 5
So 5532-44-5 is a valid CAS Registry Number.

Cyclopropanation Catalysed by RuCl2(PPh3)3 and OsCl2(PPh3)3

Demonceau, A.,Lemoine, C. A.,Noels, A. F.,Chizhevsky, I. T.,Sorokin, P.V.

, p. 8419 - 8422 (1995)

OsCl2(PPh3)3 is a cyclopropanation catalyst using ethyl diazoacetate with a variety of activated alkenes; OsCl2(PPh3)3 is however less active than RuCl2(PPh3)3 for the decomposition of the diazo reagent and the subsequent cyclopropanation.
