CAS 142-73-4 corresponds to Iminodiacetic Acid (IDA), with the molecular formula C ₄ H ₇ NO ₄ and a molecular weight of 133.10. It is a key intermediate and potent metal chelating agent for the production of glyphosate.

Basic Attributes
-Chinese name: Iminodiacetic Acid (also known as Dicarboxymethylamine, Aminodiacetic Acid)
-English name: Iminodiacetic Acid (IDA)
-Molecular formula/structure: C ₄ H ₇ NO ₄; SMILES: `O=C(O)CNCC(=O)O`
-Molecular weight: 133.10
-Appearance: White crystalline powder or crystal
-Melting point: 243 ℃ (decomposition)
-Solubility: Slightly soluble in water (about 2.43 g/100 mL at 5 ℃), difficult to dissolve in organic solvents such as ethanol and ether
-Density: Approximately 1.4-1.56 g/cm ³
-Storage conditions: Store at room temperature, dry and sealed, avoid mixing with acid and alkali, moisture-proof and light proof

Main purpose
1. Pesticide synthesis: As a core intermediate, it is used to manufacture herbicides glyphosate and glyphosate.
2. Chelating resin: a synthetic amino acid type ion exchange resin used for water softening and heavy metal removal.
3. Industrial additives: electroplating solution additives (improve coating uniformity), rubber anti-aging agents, surfactant intermediates.
4. Research and Electronics: Metal ion chelating agents (targeting Cd ² ⁺, Pb ² ⁺, etc.); High purity electronic grade products are used in semiconductor cleaning processes.

Safety and Attention
-Hazard: Irritable to the skin, eyes, and respiratory tract (GHS classification: skin irritation class 2, eye irritation class 2A); The LD50 in the abdominal cavity of mice is approximately 250 mg/kg.
-Protection requirements: Wear protective gloves, goggles, and masks during operation; If accidentally touched, rinse immediately with plenty of water.
-Environmental risk: There is potential harm to the water environment, and waste needs to be disposed of by professional institutions.
