Ammonium dodecyl sulfate(CAS: 2235-54-3)

Ammonium dodecyl sulfate (CAS: 2235-54-3) is a white to off-white crystalline powder. It has a molecular weight of approximately 328.4 g/mol. This compound is soluble in water and has a low solubility in organic solvents. It is mildly basic and can act as a surfactant, exhibiting moderate reactivity with bases and acids. It decomposes at high temperatures, releasing ammonia and fatty acid salts.

Ammonium dodecyl sulfate (CAS: 2235-54-3) is synthesized through the reaction of dodecyl alcohol and ammonia in the presence of a suitable catalyst, such as sulfuric acid or phosphoric acid. The process involves the sulfation of dodecyl alcohol followed by neutralization with ammonia. The yield is typically high, and the product is isolated by washing and drying.

Ammonium dodecyl sulfate (CAS: 2235-54-3) is widely used in the pharmaceutical industry for surfactant applications, as a stabilizer in emulsions, and in the formulation of topical medications. It is also employed in the polymer industry for emulsion polymerization and as a thickening agent. Additionally, it finds applications in the semiconductor industry as a cleaning agent and in the manufacturing of sensors due to its surfactant properties.

When handling Ammonium dodecyl sulfate (CAS: 2235-54-3), it is essential to wear appropriate personal protective equipment (PPE), including gloves and safety glasses. This compound should be stored in a cool, dry place away from heat and ignition sources. It should be handled in a well-ventilated area or a fume hood to avoid inhaling the dust. In case of a spill, it should be cleaned up using proper procedures, and the Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) should be consulted for detailed guidance.
