Diazene, 1-azulenylphenyl-, also known as 1-(1H-Azulen-1-yl)-2-phenylhydrazine, is an organic compound with the chemical formula C17H14N2. It is a derivative of diazene, which is a diatomic molecule consisting of two nitrogen atoms bonded together. The 1-azulenylphenyl diazene features an azulene ring attached to a phenyl group, with a hydrazine functional group connecting the two aromatic systems. Diazene, 1-azulenylphenyl- is of interest in organic chemistry and materials science due to its unique structure and potential applications in the synthesis of various compounds and materials. It is important to note that diazenes are generally sensitive to air and moisture, and thus require careful handling and storage.

7206-62-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7206-62-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,0 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7206-62:
(6*7)+(5*2)+(4*0)+(3*6)+(2*6)+(1*2)=84
84 % 10 = 4
So 7206-62-4 is a valid CAS Registry Number.

Azo-azulene derivatives as second-order nonlinear optical chromophores

Lacroix, Pascal G.,Malfant, Isabelle,Iftime, Gabriel,Razus, Alexandru C.,Nakatani, Keitaro,Delaire, Jacques A.

, p. 2599 - 2608 (2007/10/03)

The molecular and solid state nonlinear optical (NLO) properties of several (phenylazo)-azulenes are investigated. In particular, (4-nitrophenylazo)-azulene (2b) exhibits a quadratic hyperpolarizability (β(vec)) of 80 x 10-30 cm5 esu recorded at 1.907 μm by the electric field-induced second-harmonic (EFISH) technique. This molecular material, which crystallizes in the monoclinic noncentrosymmetric space group Pc, exhibits an efficiency 420 times that of urea in second-harmonic generation. The origin of the optical nonlinearity in azo-azulene is discussed in relation with crystal structures and semiempirical calculations within the INDO/SOS formalism, and compared with that of the well known disperse red one (DR1) organic dye.

Halogenation of 1-arylazo-azulenes

Razus, Alexandru C.,Birzan, Liviu,Razus, Stefan A.,Horga, Viorica

, p. 235 - 248 (2007/10/03)

The present investigation represents a study of the halogenation of 1-arylazo-azulenes with elemental halogens, with N-bromosuccinimide and with cupric halides with a view to synthesize the halogenated compounds and to establish the reaction mechanisms. T
