Formula: C20H14BrFS
Weight: Approx. 385.29 g/mol
Purity: Over 98% (by HPLC)
Impurities: Trace solvents possible (acetonitrile, DCM, or others used in synthesis)
Other Components: Not applicable, single-component substance
Inhalation: Remove person to fresh air, keep at rest; medical attention if symptoms develop
Skin Contact: Wash immediately with soap and water; remove contaminated clothing; seek care for lingering irritation
Eye Contact: Rinse eyes under running water for at least 15 minutes, lifting eyelids occasionally; consult physician if pain, redness, or vision changes occur
Ingestion: Rinse mouth with water without swallowing; seek prompt medical advice; do not induce vomiting unless medically directed
Main Symptoms: Potential respiratory or skin sensitization, nausea, eye irritation
Suitable Extinguishing Media: Dry chemical, foam, CO2, water spray (use caution with water in case of reactivity)
Specific Hazards: Combustion may create toxic vapors including hydrogen bromide, sulfur oxides, fluorinated compounds
Protective Equipment: Firefighters need full turnout gear, self-contained breathing apparatus
Special Procedures: Move uninvolved containers away from fire zone, avoid runoff into drains
Explosion Risk: Minimal under standard storage; dust forms may create combustible clouds
Personal Precautions: Use gloves and goggles; avoid inhaling dust; ventilate area
Environmental Precautions: Prevent from entering soil, waterways, or drains; sweep up spilled material without creating dust
Cleanup Methods: Collect into suitable container for proper disposal; wash area with soap and water after visible residue is gone
Decontamination: Wash tools and surfaces thoroughly; avoid mixing with incompatible materials
Handling: Use in a fume hood or well-ventilated area; minimize exposure by wearing gloves and safety glasses; avoid generation of dust
Storage: Keep in a tightly sealed vial or drum, protected from light, humidity and extreme temperatures; store away from oxidizers, acids, and bases
Hygiene: Wash hands and forearms after use; do not wear contaminated clothing outside work area; restrict handling to trained personnel
Exposure Limits: No occupational exposure limits established due to novelty; treat as a hazardous lab chemical
Controls: Use ventilated enclosures or fume hoods for handling powders; avoid inhaling dusts
Personal Protection: Nitrile or chemical-resistant gloves; splash goggles or face shield; disposable lab coat; respiratory protection if dust or fumes may form
Environmental Controls: Avoid release to environment; handle solid and waste material as chemical waste
Appearance: Pale yellow to off-white powder or crystalline solid
Odor: No distinctive odor
Melting Point: 120–135°C (estimated)
Boiling Point: Not determined
Solubility: Insoluble in water; soluble in DMSO, DMF, and common organic solvents
pH: Not applicable (neutral organic solid)
Flash Point: Not established
Vapor Pressure: Negligible at ambient temperature
Partition Coefficient: Data not available
Autoignition Temperature: Data not available
Decomposition: May release toxic gases on heating
Chemical Stability: Stable at room temperature if sealed and protected from moisture/oxidizers
Reactivity: Reacts with strong oxidizing agents or strong acids
Decomposition Products: Hydrogen bromide, sulfur oxides, fluorinated organic compounds if burned or heated
Hazardous Polymerization: Not anticipated
Incompatibilities: Avoid alkalis, acids, oxidizers, and conditions causing thermal decomposition
Acute Toxicity: Not fully tested; related compounds suggest possible moderate toxicity by inhalation and ingestion
Skin Irritation: Potential for irritation or allergic reaction
Eye Irritation: Dust contact could cause transient redness or discomfort
Sensitization: Repeated contact may drive sensitization in susceptible individuals
Long-Term Effects: No data, but benzyl and thiophene derivatives sometimes show organ-specific toxicity after chronic exposure
Carcinogenicity: No long-term studies; not classified as a carcinogen
Mutagenicity: Not evaluated
Reproductive Toxicity: Not evaluated
Ecotoxicity: Not studied directly; minor spills unlikely to cause visible harm, but persistent organic compounds should be kept away from soil and water due to possible bioaccumulation
Persistence and Degradability: Expected to degrade slowly in environment; halogenated and aromatic content may resist rapid breakdown
Bioaccumulation: Possible due to lipophilic structure
Mobility in Soil: Not estimated, but likely to bind tightly to sediments;
Other Hazards: Avoid uncontrolled release to environment as a precaution
Disposal Method: Collect all unused material, spill residues, and cleanup media as hazardous waste; hand over to licensed chemical disposal contractor
Container Disposal: Triple-rinse or incinerate used containers according to local regulation
Waste Code: Not assigned for this substance; default to non-specific organic chemical code
Precaution: Never flush to surface water or general landfill; incineration with environmental emission controls preferred
UN Number: Not assigned
Proper Shipping Name: Laboratory chemical, n.o.s.
Transport Hazard Class: Not classified due to lack of large-scale data
Packing Group: Not determined; support strong, sealed packaging
Marine Pollutant: Not tested; treat with care to avoid water shipment or spillage
Special Precautions: Keep dry and contained, label as "for research use only" on shipments
TSCA: Not listed on US TSCA inventory due to research status
DSL/NDSL: Not listed in Canadian inventories
EU REACH Status: Not registered; research quantity exemption may apply
OSHA Classification: Treated as hazardous by criteria for laboratory use
