24742-30-1 Usage
General Description
4'-Ethoxybenzylidene-4-cyanoaniline, also known as 4EBC, is a chemical compound commonly used as a UV absorber in plastics and adhesives. It belongs to the class of benzylidene malononitrile compounds and is typically used to protect polymers and other materials from the harmful effects of UV radiation. 4EBC is known for its ability to efficiently protect against photo-oxidation, photo-yellowing, and degradation caused by exposure to sunlight. It is characterized by its strong UV absorption properties and high thermal stability, making it a popular choice for various industrial applications. However, it is important to handle 4EBC with care due to its potential toxicity and environmental impact.
Check Digit Verification of cas no
The CAS Registry Mumber 24742-30-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,7,4 and 2 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 24742-30:
(7*2)+(6*4)+(5*7)+(4*4)+(3*2)+(2*3)+(1*0)=101
101 % 10 = 1
So 24742-30-1 is a valid CAS Registry Number.

Magnetic Susceptibility and Order Parameter of EBCA
Choudary, L. V.,Rao, J. V.,Kishore, P. R.,Venkatacharyulu, P.
, p. 173 - 177 (2007/10/02)
The variation of magnetic susceptibility (γg) as a function of temperature of the liquid crystal EBCA is reported in isotropic liquid, nematic and solid phases γg and S Δγg undergo sudden changes at the phase transformations.The isotropic liquid-nematic transition is assigned to be of first order phase transition.The order parameter is calculated using an estimated value for the molar sucseptibility anisotropy.
