Trans-octalin dibromide is a chemical compound with the molecular formula C8H12Br2. It is a dibromide derivative of trans-octalin, which is a bicyclic hydrocarbon consisting of a cyclohexane ring fused to a cyclopropane ring. The two bromine atoms are attached to different carbon atoms in the cyclohexane ring, resulting in a trans configuration. trans-octalin dibromide is often used as a synthetic intermediate in the preparation of various organic compounds, particularly those containing octalin structures. Due to its reactive bromine atoms, trans-octalin dibromide can undergo a range of chemical reactions, such as nucleophilic substitution, making it a valuable building block in organic synthesis.

704-57-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 704-57-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 704-57:
(5*7)+(4*0)+(3*4)+(2*5)+(1*7)=64
64 % 10 = 4
So 704-57-4 is a valid CAS Registry Number.

Synthesis of poly(decahydro-2-naphthyl methacrylate)s with different geometric structures and effects of side-group dynamics on polymer properties investigated by thermal and dynamic mechanical analyses and DFT calculations

We prepared the geometric isomers of decahydro-2-naphthols as the source materials for the synthesis of poly(decahydro-2-naphthyl methacrylate)s [poly(DNMA)-I, -II, -III, and -IV] including alicyclic ester groups with different geometric structures. The geometry and conformational dynamics of the decahydro-2-naphthyl moieties were investigated by NMR spectroscopy and DFT calculations. We synthesized each isomer of the methacrylic monomers, polymerized them, and investigated the optical, thermal, and mechanical properties of poly(DNMA)s with different isomer compositions. The Tg values of the poly(DNMA)s were in the following order: 139.3 C for poly(DNMA)-II 3/g, 1.489, and 42-44, respectively.
