Cyclononadecan, also known as C19H38, is a cyclic alkane consisting of 19 carbon atoms arranged in a ring structure. It is a member of the cycloalkane family, which are saturated hydrocarbons with a closed carbon chain. Cyclononadecan is a colorless, odorless, and non-polar liquid at room temperature, and it is insoluble in water but soluble in organic solvents. Cyclononadecan is primarily used as a solvent, a chemical intermediate, and in the synthesis of various organic compounds. Due to its high molecular weight and cyclic structure, cyclononadecan exhibits unique physical and chemical properties compared to its linear alkane counterparts, making it an interesting subject for research and industrial applications.

296-44-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 296-44-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 6 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 296-44:
(5*2)+(4*9)+(3*6)+(2*4)+(1*4)=76
76 % 10 = 6
So 296-44-6 is a valid CAS Registry Number.

Metathesis of cyclic alkanes catalyzed by the new surface complex [(ΞSiO)W(Me)5] affords a wide distribution of cyclic and macrocyclic alkanes. The major products with the formula CnH2n are the result of either a ring contraction or ring expans

Catalytic ring expansion, contraction, and metathesis-polymerization of cycloalkanes

Ahuja, Ritu,Kundu, Sabuj,Goldman, Alan S.,Brookhart, Maurice,Vicente, Brian C.,Scott, Susannah L.

Tandem dehydrogenation-olefin-metathesis catalyst systems, comprising a pincer-ligated iridium-based alkane dehydrogenation catalyst and a molybdenum-based olefin-metathesis catalyst, are reported to effect the metathesis-cyclooligomerization of cyclooctane and cyclodecane to give cycloalkanes with various carbon numbers, predominantly multiples of the substrate carbon number, and polymers.
