3-Bromotoluene CAS 591-17-3

1. 3-Bromotoluene is a versatile building block in organic synthesis, serving as an intermediate for the production of pharmaceuticals, agrochemicals, dyes, and other specialty chemicals . It is used as a solvent for fats, waxes, and resins .
2. 3-Bromotoluene CAS 591-17-3 is employed in scientific research for precise analytical techniques, such as the determination of bromine isotope ratios in organic compounds using advanced mass spectrometry (MC-ICPMS) .
3. Applications of 3-Bromotoluene also include its use in palladium-catalyzed reactions, such as cyanation with K₄[Fe(CN)₆] and reactions with alkynyltriarylborates to form complex organic molecules .

1. Store 3-Bromotoluene in a tightly sealed container in a cool, dry, and well-ventilated place, away from heat, sparks, and open flames . It is light-sensitive, so it should be protected from light, and a storage temperature below 15°C is recommended .
2. Keep 3-Bromotoluene away from strong oxidizing agents, as it is incompatible . To prevent static discharge and fire, ensure containers and receiving equipment are grounded and bonded, and use non-sparking tools .
3. Always 3-Bromotoluene CAS 591-17-3 use appropriate personal protective equipment (PPE) including chemical-resistant gloves (e.g., fluorinated rubber or nitrile), safety goggles with face shield, and protective clothing . Use only with adequate ventilation (fume hood) and avoid breathing vapors, mist, or dust .

1. Immediately isolate the spill area, eliminate all ignition sources, and evacuate personnel to safe areas . Contain 3-Bromotoluene using inert, non-combustible absorbent material (e.g., dry sand, earth, diatomaceous earth) and do NOT let it enter drains or waterways .
2. Carefully collect 3-Bromotoluene CAS 591-17-3 using non-sparking tools or an explosion-proof vacuum cleaner, and place it into sealed, labeled chemical waste containers for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear full chemical-protective equipment including self-contained breathing apparatus (SCBA) during cleanup . 3-Bromotoluene is classified for transport (UN1993, Hazard Class 3, PG III) and requires hazardous waste disposal .

1. 3-Bromotoluene is classified as a flammable liquid and vapor (H226) with a flash point of 60°C . It is harmful if swallowed (H302, LD50 oral rat 1540 mg/kg) , causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .
2. 3-Bromotoluene is toxic to aquatic life with long-lasting effects (H411) . Inhalation of high concentrations can cause central nervous system (CNS) depression . Thermal decomposition or combustion produces toxic and irritating fumes including carbon oxides and hydrogen bromide gas .
3. Always consult 3-Bromotoluene CAS 591-17-3 the specific Safety Data Sheet (SDS) for 3-Bromotoluene for complete hazard information, first-aid procedures (P305+P351+P338 for eyes, P301+P312+P330 for ingestion, P303+P361+P353 for skin, P304+P340 for inhalation), and handling instructions .
