3-[3-[4-(4-bromophenyl)phenyl]-1,2,3,4-tetrahydronaphthalen-1-yl]-4-hydroxychromen-2-one

3-[3-[4-(4-bromophenyl)phenyl]-1,2,3,4-tetrahydronaphthalen-1-yl]-4-hydroxychromen-2-one is a complex organic compound with CAS number 56073-10-0 and molecular formula C31H23BrO3. This brominated aromatic compound has a molecular weight of 523.4 g/mol and contains multiple ring structures including tetrahydronaphthalene and chromen-2-one moieties. It is classified as an extremely hazardous substance requiring specialized handling due to its high toxicity profile.

This compound is a solid organic material with a complex molecular structure containing bromine, oxygen, and multiple aromatic rings. With its molecular weight of 523.4 g/mol and hydrophobic aromatic structure, it likely exhibits low water solubility and high lipophilicity. The presence of the hydroxyl group on the chromen-2-one ring may provide some polar character, while the brominated biphenyl moiety contributes to its stability and persistence.

This compound is primarily used in specialized research applications and pharmaceutical intermediate synthesis due to its complex molecular structure. Its specific aromatic configuration makes it valuable for studying structure-activity relationships in medicinal chemistry. However, due to its extremely high toxicity classification (Acute Tox. 1) and reproductive toxicity (Repr. 1A), its use is strictly limited to controlled laboratory environments with appropriate safety measures.

This substance requires maximum protective measures due to its Acute Tox. 1 classification across multiple exposure routes. Full protective equipment including supplied-air respirators, chemical-resistant gloves, and full body protection is mandatory. Work must be conducted in a fume hood or controlled atmosphere with emergency shower and eyewash stations immediately accessible. Only trained personnel should handle this material, and exposure monitoring is essential.

This compound must be stored in a locked, temperature-controlled facility with restricted access due to its extreme toxicity. Storage should be in original containers in a well-ventilated, dry area away from heat sources and incompatible materials. Secondary containment is recommended to prevent environmental release. Given its STOT RE 1 and aquatic toxicity classifications, storage areas must have appropriate spill containment and emergency response equipment readily available.

Immediate medical attention is required for any exposure due to the Acute Tox. 1 classification. For skin contact, remove contaminated clothing and flush with copious amounts of water for at least 15 minutes. If inhaled, move to fresh air immediately and provide oxygen if breathing is difficult. For eye contact, flush with water for at least 15 minutes. Seek emergency medical care immediately and provide the safety data sheet to medical personnel.

This substance requires disposal as hazardous waste through authorized waste management companies due to its extreme toxicity and environmental hazard classifications. High-temperature incineration at licensed facilities is typically required. The Aquatic Acute 1 and Aquatic Chronic 1 classifications prohibit discharge to water systems. All disposal must comply with local, national, and EU waste regulations, and waste manifests must be maintained for regulatory compliance.

This substance is classified under ADR Class 6.1 (Toxic Substances), Packing Group I, indicating maximum transport restrictions. Specialized hazardous materials carriers and UN-approved packaging are mandatory. Transport documents, emergency response information, and proper labeling with GHS06, GHS08, and GHS09 pictogrammes are required. Drivers must have appropriate hazmat certifications, and vehicles must carry spill response equipment and emergency contact information.

This compound is subject to extensive regulatory oversight under EU REACH, CLP, and national chemical legislation due to its extreme hazard profile. The Repr. 1A classification may trigger authorization requirements under REACH Annex XIV. Transport is regulated under ADR/RID, and occupational exposure limits apply under workplace safety directives. While not currently listed as SVHC, its hazard profile suggests potential future regulatory restrictions on manufacturing, import, and use.

OYSI serves as a specialized European distributor for this highly regulated compound, providing compliant supply chains for authorized research institutions and pharmaceutical companies. Due to the extreme hazard classification, procurement requires verification of proper handling facilities, trained personnel, and appropriate waste disposal arrangements. OYSI ensures full regulatory compliance including proper documentation, safety data sheets, and transport arrangements meeting ADR Class 6.1 requirements.
