13440-25-0 Usage
General Description
(1,2-dinitro-2-phenyl-ethyl)benzene is a chemical compound with the molecular formula C14H10N2O4. It is a yellow crystalline solid with a strong odor, and is also known by the trade name "Fluorodifen." (1,2-dinitro-2-phenyl-ethyl)benzene is a substituted nitrobenzene derivative and is primarily used as an herbicide to control broadleaf weeds and grasses in a variety of crops. It works by inhibiting the enzyme protoporphyrinogen oxidase, which is essential for the synthesis of chlorophyll in plants. However, it should be handled with care, as it is toxic to aquatic organisms and may have harmful effects on human health if not used properly. Additionally, it is important to be aware of local regulations and guidelines regarding its use and disposal to minimize environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 13440-25-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,4 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 13440-25:
(7*1)+(6*3)+(5*4)+(4*4)+(3*0)+(2*2)+(1*5)=70
70 % 10 = 0
So 13440-25-0 is a valid CAS Registry Number.

UNSYMMETRICAL CONNECTIVE OLEFINATION BY KORNBLUM NITRO-SYNTHESIS : APPLICATIONS IN PHYTUBERIN CHEMISTRY
Crombie, Leslie,Roughley, Brian S.
, p. 3147 - 3156 (2007/10/02)
Kornblum unsymmetrical olefin synthesis employing radical-anion chain crossed-coupling (light catalysed) of a mono- and a gem-di-nitro-compound, followed by reductive NO2 removal, is examined in the context of a hindered olefin structure required for phytuberin synthesis.Whilst successful for a tetrasubstituted olefin model (for which a Witting approach failed), increasing substitution on the β-position of the mono-nitro component supressed the coupling reaction, presumably for steric reasons.An alternative coupling involving a bromonitrocyclohexane and a mononitroacetal caused symmetrical coupling of the mononitro-component in high yield, rather than a crossed reaction.Reductive elimination (using Na2S/DMF) from either rac.- or meso- 1,2-dinitro-1,2-diphenylethane leads to (E)-stilbene 98percent (E) > probably through a stabilised radical or anion.A convenient preparation of triphenylisoxazoline-N-oxide is reported.
