CAS NO.: 54960-65-5; 4-((1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)amino)butane-1-sulfonic acid. PROPERTIES: 4-((1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)amino)butane-1-sulfonic acid exists as a white crystalline powder with notable acid-base characteristics. This molecule combines a sulfonic acid group with a hydroxylated amino alcohol moiety, creating a versatile building block. Its molecular formula of C8H17NO6S corresponds to a molecular weight of approximately 255.29 g/mol. The compound demonstrates high water solubility (>100 g/L) due to the presence of multiple ionizable groups. Thermally stable up to 180 C, decomposition occurs at higher temperatures with potential release of sulfur oxides. 4-((1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)amino)butane-1-sulfonic acid should be stored between 2-8 degree Celsius to preserve its labile hydroxyl groups. When handling, care should be taken to avoid inhalation of dust and direct skin contact. The compound's acidic nature requires neutralization with bases for certain applications. In case of eye contact, immediate flushing with water for 15 minutes is recommended. The substance poses minimal fire hazard but should be stored away from strong oxidizing agents. APPLICATIONS: 4-((1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)amino)butane-1-sulfonic acid functions as a specialty buffer in biochemical assays, particularly in systems requiring pH control between 6.5-8.5. Its unique structure enables chelation of metal ions, making it valuable in enzymatic reaction studies. Researchers utilize this compound in the synthesis of glycosylation reagents due to its hydroxylated backbone. The sulfonic acid group provides excellent water solubility to derivatives, enhancing bioavailability in medicinal applications. 4-((1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl)amino)butane-1-sulfonic acid serves as a building block in the development of antiviral agents, where its multiple hydroxyl groups facilitate hydrogen bonding with target proteins. The compound's ability to form stable complexes with transition metals extends its utility to catalytic systems. Proper cold storage (2-8 C) maintains the integrity of its hydroxyl and sulfonic acid groups, ensuring consistent performance in analytical and synthetic applications.
