3,6-Dihydroxyphthalonitrile (C8H4N2O2), with a molecular weight of 160.13 and a specific density near 1.48 g/cm³, sees consistent demand from dye, pigment, and advanced material sectors. Engineers and chemists appreciate its structure: a benzene ring with cyano and hydroxyl groups, making it a valuable intermediate for phthalocyanine pigment production and specialty polymers.
China supplies a significant share of the global market, offering scalable volumes through direct chemical manufacturers and suppliers. Buyers often look at FOB or CIF terms for logistics flexibility, especially for container shipments to the EU, US, and Middle East. Inquiries tend to focus on minimum order quantity (MOQ), delivery schedule, and whether factories offer REACH pre-registered or ISO 9001-certified batches. Quick quote turnarounds happen through verified suppliers who share current policies and price updates.
HS Code for 3,6-Dihydroxyphthalonitrile falls under 2926.90.9090. Factories provide SDS, MSDS, REACH, and TDS at request, responding to stricter global import controls and customer audits. More industries ask for halal and kosher certificates, which some Chinese OEMs can deliver, especially large outfits with in-house compliance staff. SGS or third-party inspection accompanies export shipments to satisfy due diligence and buyer documentation needs.
This raw material comes as an off-white to pale-yellow powder, stable under dry storage but classed as harmful if mishandled. As a hazardous substance, safe handling includes sealed drums, ventilation, and nitrile gloves in prep areas. Larger buyers request solution-ready concentrations to cut processing time, so factory flexibility plays a role in winning orders.
MSDS safety sheets flag inhalation and long-term exposure risks, stressing the importance of local training and emergency measures. Factories sometimes provide on-site demos for new buyers rolling out material in scale batches.
Phthalocyanine pigment synthesis, polymer additives, and fine chemical formulations drive most purchase inquiries. Smaller coatings and materials science labs ask for sample volumes—for example, 500 g up to 5 kg. Larger consumer product companies negotiate batch MOQs from 100 kg up to several metric tons, pulling factory quotes to benchmark against European and Indian suppliers. Free samples, offered by some China-based suppliers, help new buyers compare purity and performance benchmarks.
Evolving safety policies across Asia and the EU mean supply chains see new rules on storage, documentation, and environmental controls. REACH pre-registration can unlock value for EU-bound orders, while ISO and halal/kosher certification affect food contact and cosmetics use. Manufacturers who keep up with documentation and third-party certification win more repeat business. Buyers’ questions have shifted to cover long-term supply assurance, factory insurance, and ready access to safety documentation.
Sourcing 3,6-Dihydroxyphthalonitrile from China remains practical for many companies, but the best outcomes happen when buyers take time to check certification, quality standards (SGS, ISO), and direct communication with the actual producing factory. Pricing stays competitive, with buyers able to push for free samples and flexible terms, especially for initial projects or expanded bulk orders. Firms ready to share transparent MSDS, traceable QC data, and prompt responses keep ahead of new policy shifts and help customers reduce risk.
