3-Ethyl-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid is a complex organic compound with the molecular formula C17H14O4. It is a derivative of chromene, a heterocyclic compound with a benzene ring fused to a pyran ring. The structure features an ethyl group at the 3-position, a phenyl group at the 2-position, and a carboxylic acid group at the 8-position. 3-ethyl-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid is characterized by its 4-oxo functionality, indicating the presence of a carbonyl group. It is likely to be a white crystalline solid and may have applications in the pharmaceutical or chemical industries, potentially as an intermediate in the synthesis of more complex molecules. The specific properties, such as solubility, stability, and reactivity, would depend on the context in which 3-ethyl-4-oxo-2-phenyl-4H-chromene-8-carboxylic acid is used.
The CAS Registry Mumber 6608-28-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,0 and 8 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6608-28: (6*6)+(5*6)+(4*0)+(3*8)+(2*2)+(1*8)=102 102 % 10 = 2 So 6608-28-2 is a valid CAS Registry Number.
