Commercial Information
Storage & Shipping
Storage Conditions
Store tightly closed in a cool, dry, ventilated and access-controlled area. Separate from strong oxidizers and protect from moisture, heat and strong light. Avoid airborne powder during opening and transfer.
Packaging Integrity
Inspect carton strength, inner liners, pallet wrapping and closures before unloading. Keep packages dry and prevent impact damage; retain legible lot labels and reseal after sampling.
Packaging
25 kg net cartons on pallets
Handling & Protection
Use enclosed powder transfer and effective local exhaust. Wear suitable chemical-resistant gloves, eye protection and protective clothing. Use properly selected particulate respiratory protection where exposure cannot be controlled. Avoid inhalation, skin contact and ingestion.
What Is 3-Bromobenzanthrone?
3-Bromobenzanthrone is a brominated aromatic ketone used as an intermediate in vat dye and pigment production. CAS 81-96-9 and EC 201-390-7 identify this material; the molecular formula is C17H9BrO and molecular weight is 309.16 g/mol. ZXCHEM supplies yellowish-brown powder with assay greater than 95.0%.
The local 2026 TDS specifies benzanthrone and 3,9-dibromobenzanthrone each below 1.5%, pH 6–7 and melting range 164–166°C. The material dissolves in concentrated sulfuric acid. Retain the stated impurity identities and test conditions when comparing the supply specification with an incoming batch COA.
Dye manufacturers evaluate this intermediate in technically supervised vat dye synthesis, including reducing gray 3T and reducing olive green B systems. It can also be assessed in related dye and pigment intermediate processes. Select reaction conditions and containment for the actual process rather than inferring performance from assay alone.
Packing follows the preferred local TDS: 25 kg net cartons on pallets. Keep tightly closed, cool and dry, away from oxidizers, strong light and heat. The matched substance reference is non-dangerous goods for transport but identifies harmful ingestion, toxic inhalation and sensitization hazards. Use enclosed transfer and effective dust extraction.
