2,4-dinitro-benzenesulfonic acid propyl ester is an organic compound with the chemical formula C9H10N2O6S. It is derived from 2,4-dinitrobenzenesulfonic acid, where a propyl group replaces the hydrogen atom on the sulfonic acid group. 2,4-dinitro-benzenesulfonic acid propyl ester is characterized by the presence of two nitro groups (-NO2) at the 2 and 4 positions on the benzene ring, and a propyl ester group (-CH2CH2CH3) attached to the sulfonic acid. It is a yellow crystalline solid and is used in the synthesis of dyes and as an intermediate in the production of certain pharmaceuticals. Due to its chemical structure, it may exhibit properties such as low solubility in water and high reactivity with nucleophiles, making it a potentially useful compound in various chemical processes.
The CAS Registry Mumber 3317-83-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,1 and 7 respectively; the second part has 2 digits, 8 and 3 respectively. Calculate Digit Verification of CAS Registry Number 3317-83: (6*3)+(5*3)+(4*1)+(3*7)+(2*8)+(1*3)=77 77 % 10 = 7 So 3317-83-7 is a valid CAS Registry Number.
