33924-76-4 Usage
General Description
N-HEPTYL 4-(4'-ETHOXYPHENOXYCARBONYL)PHENYL CARBONATE is a chemical compound used in the production of organic sunscreen formulations. It is a UV filter that protects the skin from harmful UV radiation by absorbing and dissipating the energy from the sun. N-HEPTYL 4-(4'-ETHOXYPHENOXYCARBONYL)PHENYL CARBONATE is an ester of 4-(4'-ethoxyphenoxy)benzophenone-4-carboxylic acid and n-heptyl alcohol, and it is a white crystalline powder that is insoluble in water but soluble in organic solvents. It is often used in combination with other sunscreen ingredients to provide broad-spectrum protection against both UVA and UVB radiation. Additionally, it is known for its photostability, meaning it does not degrade when exposed to light, making it an effective and long-lasting ingredient in sun protection products.
Check Digit Verification of cas no
The CAS Registry Mumber 33924-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,2 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33924-76:
(7*3)+(6*3)+(5*9)+(4*2)+(3*4)+(2*7)+(1*6)=124
124 % 10 = 4
So 33924-76-4 is a valid CAS Registry Number.

Liquid crystals V.Nematic materials derived from p- alkylcarbonato- p- alkoxyphenyl benzoates
CASTELLANO JA,MCCAFFREY MT,GOLDMACHER JE
, p. 345 - 366 (2007/10/14)
In a continued effort to synthesize materials which exhibit nematic behavior at room temperature, homologous p- alkylcarbonato- p- alkoxyphenyl benzoates were prepared. Of the 48 compounds that were synthesized 27 exhibited enantiotropic and 14 manotropic nematic properties while only 7 were not liquid crystalline. One binary mixture of anantiotropic derivatives had a nematic range of 27 to 73 C while a ternary mixture exhibited nematic behavior between 24 and 76 C. In addition, seven other mixtures had crystal to nematic transition temperatures below 30 C.
