O-Phthalodinitrile shows up in the world of chemical manufacturing under several names. Many call it phthalonitrile or 1,2-dicyanobenzene. As a raw material, phthalonitrile carries the formula C8H4N2. It weighs in at 128.13 g/mol. If you’ve handled it, you know it presents as a pale solid, mostly in powder or crystalline form. Its melting point hovers around 140°C, and it supports several downstream syntheses, especially in the creation of dyes, pigments, and high-performance polymers. The molecular structure stands simple but powerful—two nitrile (–CN) groups on a benzene ring, making it reactive and valuable for modern chemistry labs. Density clocks in at about 1.19 g/cm³. The HS Code usually picked up by customs for O-Phthalodinitrile is 2926909090.
Manufacturers in China play a big role when it comes to supplying high-quality O-Phthalodinitrile for global buyers. This chemical travels from certified factories in China to labs and factories in Europe, the US, India, and the Middle East under CIF or FOB shipping terms. MOQ (minimum order quantity) probably starts around 100 kilograms, but small sample supplies are often available. Experienced exporters often back up every shipment with MSDS, TDS, REACH, and ISO documentation. SGS, HALAL, and KOSHER certifications aren’t uncommon since more buyers demand these proofs. Safe supply chains rely on consistent packaging, with drums or bulk bags lined for containment.
If you’ve seen O-Phthalodinitrile’s MSDS, it’s clear this is not a chemical for careless handling. It shows harmful health effects—skin contact, inhalation, and accidental spills all pose risks. A ventilated work area, nitrile gloves, and safety goggles go from “optional” to non-negotiable. Keeping a hard copy of the MSDS in the workspace helps. Many plant managers I know run periodic safety drills just to keep protocols fresh. Regulatory compliance doesn’t stop at REACH or SDS—buyers in Europe and North America keep an eye out for local hazardous material rules. Responsible shipping means companies declare the right HS Code and mark outer packaging with proper hazard labels. This basic process protects workers and the environment.
As a building block, O-Phthalodinitrile lays down the backbone for phthalocyanine dyes—those vivid blues and greens in inks and plastics. Beyond colorants, engineers count on it during synthesis of advanced polymers and specialty resins. Its strong thermal stability backs up the performance in high-end composite materials. For researchers, its behavior as a nucleophile lets them take synthesis in new directions, experimenting safely because the material specs remain consistent from certified suppliers.
Factory-direct pricing draws buyers to China-based manufacturers, who balance competitive quotes with strict product quality. New buyers ask for samples before bulk orders, checking both real-world performance and documents such as MSDS and TDS for due diligence. Buyers regularly compare offers on online chemical trading platforms, checking for lead time, MOQ, and included shipping terms. Policies on OEM, private labeling, and halal/kosher status factor into decisions, especially for multinational buyers needing compliance across markets.
The rush for documentation and certification marks a big shift in the chemical business. Savvy purchasers will keep requesting full product certificates and ISO, SGS, HALAL, or KOSHER paperwork. Demand for eco-friendly and safe manufacturing rises every year. Dialogue between buyers and suppliers—open questions, regular audits, third-party testing—drives up product reliability and workplace safety.
