(2S,3R)-2-Amino-3-hydroxy-butyric acid benzhydryl ester, also known as THAM (Toluene-4-sulfonic acid Hydrazide), is a chemical compound that is formed when (2S,3R)-2-amino-3-hydroxy-butyric acid is esterified with benzhydryl alcohol. (2S,3R)-2-Amino-3-hydroxy-butyric acid benzhydryl ester; compound with toluene-4-sulfonic acid is further combined with toluene-4-sulfonic acid, resulting in a zwitterionic compound that has both acidic and basic properties. THAM is primarily used in medical applications, particularly in the treatment of acid-base imbalances and as a urinary acidifier. It works by accepting protons (H+ ions) in the blood, thereby acting as a buffer and helping to maintain the body's pH balance. The combination with toluene-4-sulfonic acid enhances its ability to manage acid-base equilibrium, making it a valuable compound in clinical settings.
The CAS Registry Mumber 5042-87-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,4 and 2 respectively; the second part has 2 digits, 8 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5042-87: (6*5)+(5*0)+(4*4)+(3*2)+(2*8)+(1*7)=75 75 % 10 = 5 So 5042-87-5 is a valid CAS Registry Number.
