4-Hexadecyloxy-3-sulfo-benzoic acid is a synthetic organic compound with the chemical formula C23H38O6S. It is a derivative of benzoic acid, featuring a hexadecyl (C16H33) alkyl chain attached to the 4-position and a sulfonic acid group (-SO3H) at the 3-position. 4-Hexadecyloxy-3-sulfo-benzoic acid is known for its surfactant properties, particularly its ability to lower the surface tension of water, making it useful in various industrial applications such as detergents, emulsifiers, and foaming agents. Its amphiphilic nature, with a hydrophilic sulfonic acid group and a hydrophobic alkyl chain, allows it to interact with both water and oil, facilitating the dispersion of oils in water. The compound is also characterized by its anionic nature due to the presence of the sulfonic acid group, which can form salts with various cations.
The CAS Registry Mumber 2488-46-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,8 and 8 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 2488-46: (6*2)+(5*4)+(4*8)+(3*8)+(2*4)+(1*6)=102 102 % 10 = 2 So 2488-46-2 is a valid CAS Registry Number.
