o-Amino-N-phenylhippuric acid ethyl ester, also known as ethyl o-aminohippurate, is a synthetic chemical compound with the molecular formula C11H13NO3. It is derived from the parent compound o-aminohippuric acid (OAH) by esterification with ethanol. This process involves the substitution of the carboxylic acid group in OAH with an ethoxy group, resulting in an ester. The compound is used as a substrate in various medical and biochemical assays, particularly in the measurement of renal function and the activity of certain enzymes. It is also employed in the study of drug metabolism and as a model compound in pharmacological research. The esterification of OAH enhances its lipophilicity, which can affect its absorption, distribution, and metabolism in biological systems.
The CAS Registry Mumber 5871-23-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,7 and 1 respectively; the second part has 2 digits, 2 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5871-23: (6*5)+(5*8)+(4*7)+(3*1)+(2*2)+(1*3)=108 108 % 10 = 8 So 5871-23-8 is a valid CAS Registry Number.
