FAQ

What are the physical and chemical properties of Dodecyl dihydrogen phosphate (CAS: 12751-23-4)?

Dodecyl dihydrogen phosphate (CAS: 12751-23-4) is a white crystalline solid with a molecular weight of approximately 306.47 g/mol. It has a low solubility in water but is soluble in organic solvents. Chemically, it is mildly acidic and reactive, capable of forming salts with bases. It is stable under normal conditions but should be stored in a cool, dry place away from direct sunlight.

How is Dodecyl dihydrogen phosphate (CAS: 12751-23-4) typically synthesized?

Dodecyl dihydrogen phosphate (CAS: 12751-23-4) can be synthesized through the reaction of dodecyl alcohol with phosphoric acid. The process typically involves esterification under mild conditions, using acetic anhydride as a catalyst to improve yield and selectivity. The product is then purified by crystallization and recrystallization to obtain high-purity material.

What industries use Dodecyl dihydrogen phosphate (CAS: 12751-23-4)?

Dodecyl dihydrogen phosphate (CAS: 12751-23-4) is used in various industries, including pharmaceuticals, where it serves as a surfactant in drug formulations; in polymers, where it acts as a stabilizer; in sensors, where it can be incorporated as a functional material; and in semiconductors, where it is used in cleaning and etching processes.

What precautions should be taken when handling Dodecyl dihydrogen phosphate (CAS: 12751-23-4)?

When handling Dodecyl dihydrogen phosphate (CAS: 12751-23-4), always wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Store it in a well-ventilated area, preferably in a fume hood. In case of a spill, neutralize the acid with a base and clean up with appropriate absorbent materials. Refer to the safety data sheet (SDS) for detailed handling and emergency procedures.
