19230-27-4 Usage
General Description
1,3-dibromo-2-chlorobenzene is a chemical compound that belongs to the class of halogenated aromatic hydrocarbons. It is a colorless to light yellow liquid with a strong, unpleasant odor. 1,3-dibromo-2-chlorobenzene is primarily used as an intermediate in the production of pharmaceuticals, dyestuffs, and agrochemicals. It is also used as a solvent in the manufacturing of organic chemicals, and as a pesticide and fungicide. 1,3-dibromo-2-chlorobenzene is considered to be harmful if swallowed, inhaled, or absorbed through the skin, and may cause irritation to the eyes, skin, and respiratory system. It is important to handle this chemical with caution and to use appropriate protective equipment when working with it.
Check Digit Verification of cas no
The CAS Registry Mumber 19230-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,3 and 0 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19230-27:
(7*1)+(6*9)+(5*2)+(4*3)+(3*0)+(2*2)+(1*7)=94
94 % 10 = 4
So 19230-27-4 is a valid CAS Registry Number.

Biphenylene dimers, which may be considered as 'macrocyclic' 2 x 2 fragments of net 1 and dimeric fragments of a double-stranded polymer, 5, are prepared. X-ray crystallography on two polymorphs of the dimer 9 reveals that its bond alternation is analogous to that in biphenylene; the tetraphenylene part of 9 has approximately C(2h) symmetry with a small dihedral angle (.-,M+ (M = Li, K) and 92-,2M+ (M = Li, K), were generated and characterized by ESR, NMR, and UV-vis spectroscopies. The spectral data for the dianions are compatible with classical structures; no evidence for 'in-plane aromaticity' is found. For polymer 5, a localized band and large density of states near the Fermi level are found, using extended Huckel theory calculations.
