General Description
2,4-Dibromo-1,3-benzenediol, also known as 2,4-dibromoresorcinol, is a chemical compound with the molecular formula C6H4Br2O2. It is a white to off-white solid that is used primarily as a chemical intermediate in the synthesis of pharmaceuticals, dyes, and other organic compounds. 2,4-Dibromo-1,3-benzenediol is classified as a halogenated phenol, and is commonly used in chemical reactions as a precursor for the synthesis of more complex organic molecules. It is important to handle this compound with care, as it may be harmful if ingested, inhaled, or come into contact with skin.
Check Digit Verification of cas no
The CAS Registry Mumber 18011-67-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,1 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18011-67:
(7*1)+(6*8)+(5*0)+(4*1)+(3*1)+(2*6)+(1*7)=81
81 % 10 = 1
So 18011-67-1 is a valid CAS Registry Number.

Binding features of molecular clips derived from diphenylglycoluril
Sijbesma,Kentgens,Lutz,Van Der Maas,Nolte
, p. 8999 - 9005 (2007/10/02)
The structure and binding properties of a series of receptor molecules based on the building block diphenylglycoluril are described. These receptors bind dihydroxy-substituted aromatic guests in chloroform solution by means of hydrogen bonding and π-π stacking interactions. IR difference spectroscopy shows that the hydrogen bonds are formed between the OH groups of the guest molecule and the π-electrons of the urea carbonyl groups present in the receptor. The structure of the complexes was further investigated by comparing the complexation-induced shifts in the 1H NMR spectra with the calculated shifts for a number of geometries of the host-guest complexes. These data demonstrate that the guest molecules are clamped within the cavity of the receptor.
