Monothiophosphorsaeure-O,O-dimethylester-S-<2-nitro-phenylester>, also known as O,O-dimethyl monothiophosphoric acid S-2-nitrophenyl ester, is a chemical compound with the molecular formula C9H10NO5PS. It is an organophosphorus compound that belongs to the class of thiophosphates. Monothiophosphorsaeure-O,O-dimethylester-S-<2-nitro-phenylester> is characterized by the presence of a phosphorus atom bonded to a sulfur atom, a methyl group, and a 2-nitrophenyl group. It is an ester derivative, formed by the reaction of monothiophosphoric acid with methanol and 2-nitrophenol. Due to its chemical structure, it may exhibit properties such as reactivity with nucleophiles and potential applications in the synthesis of pesticides or other organophosphorus compounds. However, it is important to note that organophosphorus compounds can be toxic and require careful handling.
The CAS Registry Mumber 4184-45-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 4 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4184-45: (6*4)+(5*1)+(4*8)+(3*4)+(2*4)+(1*5)=86 86 % 10 = 6 So 4184-45-6 is a valid CAS Registry Number.
