(4-hydroxy-2,5-dimethyl-1-phenyl-phosphinan-4-yl)-phosphonic acid dibutyl ester is a complex organic compound with the molecular formula C19H29O4P2. It is a derivative of phosphonic acid, featuring a phosphorus atom bonded to a hydroxyl group, two methyl groups, and a phenyl group, all attached to a phosphorus-containing ring structure. (4-hydroxy-2,5-dimethyl-1-phenyl-phosphinan-4-yl)-phosphonic acid dibutyl ester is characterized by its two butyl ester groups, which are derived from butanol and are attached to the phosphonic acid moiety. The esterification of phosphonic acid with butanol enhances the compound's solubility and reactivity. It is used in various chemical applications, including as a reagent in organic synthesis and potentially in the production of specialty chemicals or pharmaceuticals. Due to its complexity, it is typically synthesized in a laboratory setting and requires careful handling due to its reactivity and potential toxicity.
The CAS Registry Mumber 55369-11-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,6 and 9 respectively; the second part has 2 digits, 1 and 1 respectively. Calculate Digit Verification of CAS Registry Number 55369-11: (7*5)+(6*5)+(5*3)+(4*6)+(3*9)+(2*1)+(1*1)=134 134 % 10 = 4 So 55369-11-4 is a valid CAS Registry Number.
