N2-(toluene-4-sulfonyl)-L-ornithine methyl ester hydrochloride is a chemical compound with the molecular formula C14H21ClN2O4S. It is a derivative of L-ornithine, an amino acid, where the N2 position is substituted with a toluene-4-sulfonyl group, and the carboxylic acid group is esterified with a methyl group. The hydrochloride salt form indicates that it contains a chloride ion, which is often used to improve the solubility and stability of the compound. N2-(toluene-4-sulfonyl)-L-ornithine methyl ester; hydrochloride is known for its potential applications in pharmaceutical research, particularly in the development of drugs targeting the enzyme arginase, which is involved in the urea cycle and has been implicated in various diseases. The toluene-4-sulfonyl group provides a bulky and hydrophobic character, which can influence the compound's binding properties and selectivity towards its target enzyme.
The CAS Registry Mumber 1031-48-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,3 and 1 respectively; the second part has 2 digits, 4 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1031-48: (6*1)+(5*0)+(4*3)+(3*1)+(2*4)+(1*8)=37 37 % 10 = 7 So 1031-48-7 is a valid CAS Registry Number.
