N,N-Bis(2-hydroxyethyl)stearamide(CAS: 93-82-3)

N,N-Bis(2-hydroxyethyl)stearamide (CAS: 93-82-3) is a white to slightly yellow crystalline solid with a molecular weight of approximately 394.5 g/mol. It has limited solubility in water and organic solvents. The compound is relatively stable under normal conditions but can hydrolyze in the presence of acidic or basic conditions. It is slightly soluble in ethanol and freely soluble in hot dimethylformamide (DMF).

N,N-Bis(2-hydroxyethyl)stearamide (CAS: 93-82-3) is typically synthesized by amide formation between stearic acid and ethylene glycol in the presence of a catalyst, such as sulfuric acid or p-toluenesulfonic acid. The reaction involves esterification of stearic acid followed by amide formation with ethylene glycol. The product has a high yield and good selectivity.

N,N-Bis(2-hydroxyethyl)stearamide (CAS: 93-82-3) is used in various industries due to its excellent lubricating and compatibility properties. It is commonly used in the pharmaceutical industry as a lubricant in tablet manufacturing. In the polymer industry, it serves as a compatibilizer to improve the blend properties of polymers. It is also used in the semiconductor industry as a surfactant and in the manufacture of sensors and coatings.

When handling N,N-Bis(2-hydroxyethyl)stearamide (CAS: 93-82-3), it is important to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a lab coat. Work should be conducted in a well-ventilated area or fume hood to minimize inhalation risks. Spills should be cleaned up immediately using appropriate absorbent materials. In case of skin contact, wash the affected area thoroughly with soap and water. For more detailed information, refer to the Safety Data Sheet (SDS).
