(Aminooxy)acetic acid(CAS: 645-88-5)

(Aminooxy)acetic acid is a white crystalline solid with a molecular weight of approximately 117.11 g/mol. It is slightly soluble in water and ethanol. Chemically, it is highly reactive, particularly with metal ions and reducing agents. It has a pKa of about 9.6, which influences its basicity in aqueous solutions.

(Aminooxy)acetic acid can be synthesized through the reaction of oxalic acid with hydrazine followed by hydrolysis. The process involves the use of a catalyst, typically sulfuric acid, and requires careful control of temperature and pressure to achieve high yield and selectivity.

(Aminooxy)acetic acid is used in the pharmaceutical industry as a precursor for the synthesis of various drugs. It finds applications in the polymer industry as a cross-linking agent and in the sensor industry for the development of gas sensors. Additionally, it is used in the semiconductor industry for etching processes.

When handling (Aminooxy)acetic acid, it is crucial to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. Store it in a well-ventilated area, away from heat sources. In case of a spill, use a fume hood and neutralize the acid with a base before cleaning up. Always refer to the Material Safety Data Sheet (MSDS) for additional safety information and guidelines.
