Description
Ethane-1,2-diyl palmitate, also known as Ethylene Glycol Dipalmitate, is a chemical compound derived from the esterification of ethylene glycol and palmitic acid. It is a colorless to pale yellow liquid with a slight characteristic odor. Its molecular formula is C36H70O4, and it is a nonionic, non-volatile, and thermally stable compound.
Uses
Used in Thermal Energy Storage Industry:
Ethane-1,2-diyl palmitate is used as a component of phase change materials (PCMs) for thermal energy storage. It serves as a heat storage medium that can absorb and release thermal energy during phase transitions, thus providing an efficient way to store and manage thermal energy in various applications, such as solar energy systems, building insulation, and temperature control systems.
The reason for its use in this application is due to its high heat of fusion, thermal stability, and non-corrosive nature, which make it an ideal candidate for thermal energy storage systems. Additionally, its non-flammable and non-toxic properties contribute to its safety and reliability in various industrial applications.

Check Digit Verification of cas no
The CAS Registry Mumber 624-03-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 4 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 624-03:
(5*6)+(4*2)+(3*4)+(2*0)+(1*3)=53
53 % 10 = 3
So 624-03-3 is a valid CAS Registry Number.
