715-50-4 Usage
Uses
3-Bromophenanthrene can be used as organic synthesis intermediates and pharmaceutical intermediates, mainly used in laboratory research and development processes and chemical production processes.
Synthesis
3 -bromophenanthreneTo a 250 mL vessel equipped with a pyrex inner water-cooled jacket was added l-bromo-4-[2- phenylvinyl] benzene (520 mg, 2.0 mmol) from Step 1 above, in cyclohexane (230 mL) and THF (5 mL). To this solution was added iodine (770 mg, 3.0 mmol). The stirred solution was first degassed by bubbling nitrogen and was then exposed to UV light for 16 hours by inserting a 450 W medium pressure mercury lamp in the inner insert. The reaction was quenched with 10% Na2S2?3 and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over Na2SO4 and the volatiles were removed under reduced pressure. The crude material was purified by flash chromatography on silica (100 % hexanes) to afford 3-bromophenanthrene (486 mg, 94%) as a white solid.
Check Digit Verification of cas no
The CAS Registry Mumber 715-50-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,1 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 715-50:
(5*7)+(4*1)+(3*5)+(2*5)+(1*0)=64
64 % 10 = 4
So 715-50-4 is a valid CAS Registry Number.

Selective carbon-bromine bond fission induced by non-resonant two-photon (NRTP) excitation of trans-4-bromostilbene
Miyazawa, Takashi,Liu, Chengyou,Kira, Mitsuo

Non-resonant two-photon (NRTP) excitation of a 1,4-dioxane solution of trans-4-bromostilbene induces selective homolytic carbon-bromine bond fission, in contrast to the corresponding single-photon (SP) excitation, where the cis-trans isomerization is predominant.
