3--propionsaeure-thiophenylester, also known as 3-(diethoxyphosphoryl)propionic acid thiophen-2-yl ester, is an organophosphorus compound characterized by its chemical structure that includes a phosphono group, a propionic acid moiety, and a thiophenyl ester. 3--propionsaeure-thiophenylester is a derivative of propionic acid, where the carboxylic acid group is esterified with a thiophen-2-yl group, and the resulting ester is further phosphorylated with a diethyl phosphonate group. It is a colorless liquid with a molecular formula of C11H17O5PS and a molecular weight of 294.29 g/mol. Due to its complex structure, it is typically used in specialized chemical research and synthesis, particularly in the field of organophosphorus chemistry. The compound's properties, such as its reactivity and potential applications, are of interest to chemists studying the behavior of phosphorus-containing molecules in various reactions and their potential uses in agriculture, pharmaceuticals, or materials science.
The CAS Registry Mumber 3661-24-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,6 and 1 respectively; the second part has 2 digits, 2 and 4 respectively. Calculate Digit Verification of CAS Registry Number 3661-24: (6*3)+(5*6)+(4*6)+(3*1)+(2*2)+(1*4)=83 83 % 10 = 3 So 3661-24-3 is a valid CAS Registry Number.
