615-87-2 Usage

General Description

1,5-Dibromo-2,4-dimethylbenzene, also known as 2,4-Dimethyl-1,5-dibromobenzene, is a chemical compound with the molecular formula C8H8Br2. It is a colorless to light yellow liquid that is insoluble in water but soluble in organic solvents. 1,5-Dibromo-2,4-dimethylbenzene is commonly used in organic synthesis and as an intermediate in the production of pharmaceuticals and agrochemicals. It is also used as a building block for the synthesis of various polymers and in the manufacturing of dyes and pigments. Additionally, it is utilized as a reagent in organic reactions and as a solvent in various industrial processes. However, it is important to handle this chemical with caution as it can be harmful if swallowed, inhaled, or absorbed through the skin.

Check Digit Verification of cas no

The CAS Registry Mumber 615-87-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 615-87:
(5*6)+(4*1)+(3*5)+(2*8)+(1*7)=72
72 % 10 = 2
So 615-87-2 is a valid CAS Registry Number.

Bis(silylethynylated) 5,7- and 5,12-diazapentacenes were synthesized from cis- and trans-quinacridone using protection, alkynylation and deoxygenation. The solid-state packing of the targets is determined by choice and position of the silylethynyl substit

Anion Recognition in Water by Charge-Neutral Halogen and Chalcogen Bonding Foldamer Receptors

A novel strategy for the recognition of anions in water using charge-neutral σ-hole halogen and chalcogen bonding acyclic hosts is demonstrated for the first time. Exploiting the intrinsic hydrophobicity of halogen and chalcogen bond donor atoms integrated into a foldamer structural molecular framework containing hydrophilic functionalities, a series of water-soluble receptors was constructed for an anion recognition investigation. Isothermal titration calorimetry (ITC) binding studies with a range of anions revealed the receptors to display very strong and selective binding of large, weakly hydrated anions such as I- and ReO4-. This is achieved through the formation of 2:1 host-guest stoichiometric complex assemblies, resulting in an encapsulated anion stabilized by cooperative, multidentate, convergent σ-hole donors, as shown by molecular dynamics simulations carried out in water. Importantly, the combination of multiple σ-hole-anion interactions and hydrophobic collapse results in I- affinities in water that exceed all known σ-hole receptors, including cationic systems (β2 up to 1.68 × 1011 M-2). Furthermore, the anion binding affinities and selectivity trends of the first example of an all-chalcogen bonding anion receptor in pure water are compared with halogen bonding and hydrogen bonding receptor analogues. These results further advance and establish halogen and chalcogen bond donor functions as new tools for overcoming the challenging goal of anion recognition in pure water.
