Main Applications and Upstream & Downstream Links
Core Applications:Solid iminodiacetonitrile is a key intermediate in glyphosate synthesis; it is used to produce iminodiacetic acid (IDA) and its derivatives, which are applied in fields including dyes, electroplating, water treatment and synthetic resins.
Upstream Raw Materials: Sodium/potassium cyanide, formaldehyde, ammonia/ethylenediamine (varies with production processes of solid iminodiacetonitrile).
Downstream Products: Iminodiacetic acid (IDA), N-(phosphonomethyl)iminodiacetic acid (PMIDA), glyphosate and N-substituted derivatives.
Quality Specifications and Packaging
Typical Specifications (Enterprise Internal Control): Purity ≥ 95%–98%; Melting Point 75–78℃; Loss on Drying ≤ 0.5%; Water-insoluble Matter ≤ 0.2%
Packaging: Industrial grade: 25 kg in double-layer packaging (inner plastic bag, outer woven bag) Storage and Labeling: Store in a well-ventilated and dry place; Packaging shall be labeled with manufacturer, address, product name, grade, net content, batch number/date of manufacture and trademark.
