553-45-7 Usage
General Description
1,2-bis(2-methoxyphenoxy)ethane, also known as bisphenol F dimethacrylate, is a chemical compound commonly used as a crosslinking agent in the production of adhesives, dental materials, and coatings. It is a bisphenol compound derived from the condensation of bisphenol A and formaldehyde, and it is often used in combination with other monomers or crosslinking agents to improve the flexibility, strength, and durability of various polymers. It is a clear, colorless liquid with a slightly sweet odor, and it poses a low risk of toxicity to humans when used in accordance with recommended safety practices. However, exposure to high concentrations through inhalation, skin contact, or ingestion may cause irritation, sensitization, or other health effects. Therefore, proper handling and use of 1,2-bis(2-methoxyphenoxy)ethane are recommended to minimize potential risks to human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 553-45-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,5 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 553-45:
(5*5)+(4*5)+(3*3)+(2*4)+(1*5)=67
67 % 10 = 7
So 553-45-7 is a valid CAS Registry Number.

Polybenzocrown ethers: Synthesis by cesium-assisted cyclization and solid-state structures

A series of large-ring polybenzocrown ethers is prepared by cesium-assisted cyclizations. Reactions of diphenols/bisphenols, dimesylates of oligoethylene glycols and cesium carbonate in MeCN produce the large-ring polybenzocrown ethers in high yields. To gain further insight into the structures of these compounds, solid-state structures of three large-ring crown ethers are obtained by X-ray diffraction.
