615-59-8 Usage


2,5-Dibromotoluene is an organic compound with the chemical formula C7H6Br2. It is a derivative of toluene, a methylbenzene, where two hydrogen atoms at the 2nd and 5th positions are replaced by bromine atoms. 2,5-Dibromotoluene is characterized by its bromine-substituted aromatic structure, which provides it with unique chemical and physical properties.


Used in Analytical Chemistry:
2,5-Dibromotoluene is used as an internal standard for the quantification of cyanide and thiocyanate in human saliva by Gas Chromatography-Mass Spectrometry (GC-MS). Its stable and predictable behavior under GC-MS conditions makes it an ideal candidate for accurate and reliable measurements in this application.
Used in Polymer Synthesis:
In the field of polymer chemistry, 2,5-dibromotoluene is utilized in the preparation of 2,5-bis(4′-alkoxycarbonylphenyl)styrenes. These are essential monomers required for the synthesis of mesogen-jacketed liquid-crystal polymers. The unique structure of 2,5-dibromotoluene contributes to the formation of these monomers, which are crucial for creating advanced polymer materials with specific properties and applications in various industries.

Check Digit Verification of cas no

The CAS Registry Mumber 615-59-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 615-59:
68 % 10 = 8
So 615-59-8 is a valid CAS Registry Number.

Highly efficient Sandmeyer reaction on immobilized CuI/CuII-based catalysts

Tarkhanova, Irina G.,Gantman, Michail G.,Sigeev, Alexander S.,Maslakov, Konstantin I.,Zelikman, Vladimir M.,Beletskaya, Irina P.

, p. 261 - 263 (2018/06/01)

Highly effective embodiment of Sandmeyer reaction has been revealed for Cu-based catalysts incorporating ionic liquid on Silochrom support. The most active catalyst (TOF = = 4000–8000 h–1) contains comparable amounts of cuprous and cupric chloride anions. The reported method allows one to carry out the reaction for anilines in the one-pot mode.

Halogen substituted metallocene compounds for olefin polymerization


, (2008/06/13)

A metallocene compound is represented by the formula (1): wherein: M is a Group 3, 4, 5 or 6 transition metal atom, or a lanthanide metal atom, or actinide metal atom, preferably a Group 4 transition metal atom selected from titanium, zirconium or hafnium; E is a substituted or unsubstituted monocyclic or polycyclic arenyl ligand pi-bonded to M; A is a substituted or unsubstituted polycyclic arenyl ligand that is pi-bonded to M and has a different ring structure than the E ligand; at least one of the A and E ligands includes at least one halogen substituent directly bonded to an sp2 carbon at a bondable ring position; Y is a bridging group containing at least one Group 13, 14, 15, or 16 element and any single position of the ring structure of A and to any single position of the ring structure of E; and y is zero or 1, indicating the absence (y=0) or presence (y=1) of Y; and each X is a univalent anionic ligand, or two X are joined and bound to the metal atom to form a metallocycle ring, or two X are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand; provided that when E is an unsubstituted cyclopentadienyl ligand, either y is one or A is not 2-bromofluorenyl or 2,7-dibromofluorenyl.
