2,4,5-trichloro-3,6-dimethoxybenzyl bromide is a complex organic chemical compound with the molecular formula C9H8BrCl3O2. It is characterized by the presence of three chlorine atoms at the 2, 4, and 5 positions, two methoxy groups at the 3 and 6 positions, and a bromine atom attached to the benzyl carbon. 2,4,5-trichloro-3,6-dimethoxybenzyl bromide is a halogenated derivative of benzyl bromide, which is a type of alkyl halide. It is typically synthesized for use in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals, due to its reactive halogen atoms that can participate in various chemical reactions. The compound's structure allows for a range of applications, including as an intermediate in the synthesis of more complex molecules, where its halogenated and methoxylated nature can influence the reactivity and selectivity of subsequent reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 4640-33-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,6,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4640-33:
(6*4)+(5*6)+(4*4)+(3*0)+(2*3)+(1*3)=79
79 % 10 = 9
So 4640-33-9 is a valid CAS Registry Number.

SYNTHESIS OF RIGIDLY LINKED TRIAD MOLECULES BASED ON OCTAALKYLPORPHYRIN, CAPABLE OF MULTISTEP ELECTRON TRANSFER

Gribkov, A.A.,Borovkov, V.V.,Evstigneeva, R.P.,Sakata, Y.

, p. 905 - 915 (2007/10/02)

We have designed and carried out the synthesis of triad model systems containing octaalkylporphyrin, benzoquinone, and trichlorobenzoquinone with an oxidation-reduction potential gradient in the molecule.The quinone moieties are fixed relative to the porphyrin using spirononane and methylene spacers.
