Uses
Used in Photopolymer Production:
4,4'-Diazidodiphenyl ethane is used as a photoinitiator for the production of light-sensitive polymers. It facilitates the polymerization process by decomposing and releasing nitrogen gas when exposed to light of a specific wavelength, making it a crucial component in this application.
Used in Printed Circuit Board Industry:
In the production of printed circuit boards, 4,4'-diazidodiphenyl ethane plays a significant role as a photoinitiator. Its ability to trigger polymerization upon light exposure is essential for creating the necessary layers and patterns on the circuit boards, ensuring their proper function and performance.
Used in Semiconductor Manufacturing:
4,4'-Diazidodiphenyl ethane is also utilized in the manufacturing of photoresist materials for semiconductor devices. Its role as a photoinitiator is vital in the formation of the intricate patterns and structures required in semiconductor production, contributing to the development of advanced electronic components.
Due to the explosive nature of 4,4'-diazidodiphenyl ethane, it must be handled with extreme caution and stored in a cool, dry place away from heat and light sources to ensure safety during its use in these industries.
Check Digit Verification of cas no
The CAS Registry Mumber 72695-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,9 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72695-23:
(7*7)+(6*2)+(5*6)+(4*9)+(3*5)+(2*2)+(1*3)=149
149 % 10 = 9
So 72695-23-9 is a valid CAS Registry Number.

Page/Page column 28, (2010/02/11)
The invention describes a means of enhancing the adhesion and sealant qualities of adhesives through the addition of a surface modifier. The invention has particular relevance to the adhesion and sealing of tanned leather where surface functionality suitable for effective adhesion with known adhesives is impaired by loss of functionality of the leather surface. The invention is however equally applicable to the adhesion of articles made from other materials such as plastics and plastic composites where the surface chemistry of the article requires modification for improved adhesion.
