This chemical has a molecular weight of 169.07 g/mol and contains both amino and phosphonic acid functional groups. It is classified as hazardous due to its severe eye damaging properties and chronic aquatic toxicity. The compound falls under ADR class 9 miscellaneous dangerous substances.

2-(phosphonomethylamino)acetic acid is typically a white to off-white crystalline solid at room temperature. As an amino acid derivative containing phosphonic acid groups, it is highly polar and exhibits good water solubility. The compound contains both acidic phosphonic groups and basic amino functionality, making it amphoteric. Its molecular structure allows for strong hydrogen bonding interactions with water and other polar solvents.

2-(phosphonomethylamino)acetic acid is primarily used as a chelating agent and scale inhibitor in industrial water treatment applications. It serves as an intermediate in pharmaceutical synthesis and as a building block for specialty chemicals. The compound finds applications in metal surface treatment, corrosion inhibition, and as a sequestering agent in various industrial processes. Its phosphonic acid functionality makes it valuable for binding metal ions.

2-(phosphonomethylamino)acetic acid requires careful handling due to its Eye Dam. 1 classification. Personnel must wear appropriate eye protection, chemical-resistant gloves, and protective clothing. Work should be conducted in well-ventilated areas or under fume extraction. Avoid contact with skin and eyes, and prevent inhalation of dust particles. Emergency eyewash stations should be readily accessible, and proper training on handling procedures is essential.

2-(phosphonomethylamino)acetic acid should be stored in tightly closed containers in a cool, dry, and well-ventilated area. Keep away from incompatible materials such as strong bases and oxidizing agents. Storage areas should be equipped with appropriate spill containment measures. Containers should be properly labeled and stored away from heat sources and direct sunlight. Regular inspection of storage containers for integrity is recommended.

Eye contact with 2-(phosphonomethylamino)acetic acid requires immediate and thorough rinsing with clean water for at least 15 minutes, holding eyelids open. Seek immediate medical attention due to the Eye Dam. 1 classification. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air and seek medical attention if symptoms develop. Remove contaminated clothing and wash before reuse.

2-(phosphonomethylamino)acetic acid must be disposed of in accordance with local, national, and international regulations. As a hazardous substance, it cannot be disposed of with regular waste. Contact licensed waste disposal companies for proper treatment and disposal. Consider recycling or recovery options where feasible. Waste containers should be properly labeled and stored in designated areas until collection by authorized waste management services.

2-(phosphonomethylamino)acetic acid is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III. Transport requires appropriate packaging, labeling, and documentation according to dangerous goods regulations. Packages must display the proper shipping name, UN number, and hazard labels including GHS05 and GHS09 pictograms. Personnel involved in transport must be trained in dangerous goods handling procedures.

2-(phosphonomethylamino)acetic acid is subject to CLP regulation with Eye Dam. 1 and Aquatic Chronic 2 classifications, requiring appropriate labeling with Danger signal word and GHS05/GHS09 pictograms. It falls under REACH regulation but is not listed as an SVHC (Substance of Very High Concern). Suppliers must provide safety data sheets, and users must comply with occupational safety regulations and environmental protection requirements.
