2-Bromo-5-methylbenzenamine CAS 53078-85-6

1. 2-Bromo-5-methylbenzenamine CAS 53078-85-6 is primarily used as a versatile intermediate in organic synthesis, particularly in cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig) to introduce ortho-bromo and para-methyl substituted aniline motifs into complex molecules.
2. 2-Bromo-5-methylbenzenamine serves as a key building block in the synthesis of pharmaceuticals, agrochemicals, and dyes, where the bromo and amino groups allow for further functionalization.
3. 2-Bromo-5-methylbenzenamine functions as a precursor for heterocyclic compounds, such as benzimidazoles and indoles, in medicinal chemistry and material science research.

1. Store 2-bromo-5-methylbenzenamine CAS 53078-85-6 in a cool, dry, well-ventilated area, protected from light and air, in tightly sealed, amber glass containers under an inert atmosphere (e.g., nitrogen) to prevent oxidation and degradation.
2. Keep 2-bromo-5-methylbenzenamine strictly separate from strong oxidizing agents, strong acids, acid chlorides, and reactive chemicals to avoid exothermic reactions or hazardous decomposition.
3. Handle 2-bromo-5-methylbenzenamine with extreme care using non-sparking tools and grounded equipment; ensure containers are clearly labeled and stored in a dedicated, secure area.

1. Immediately isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; avoid direct contact and prevent the material from entering drains or soil.
2. Carefully collect spilled 2-bromo-5-methylbenzenamine using a clean, dry tool or a HEPA-filter vacuum cleaner, and place it into a sealed, labeled container for disposal as hazardous chemical waste.
3. Clean the contaminated surface thoroughly with a suitable solvent or detergent under controlled conditions; collect all contaminated materials and dispose of them in full compliance with local, national, and international regulations for halogenated and toxic hazardous waste.

1. 2-Bromo-5-methylbenzenamine CAS 53078-85-6 is toxic if swallowed, inhaled, or absorbed through the skin, and may cause skin irritation, serious eye damage, and respiratory tract irritation.
2. 2-Bromo-5-methylbenzenamine may cause methemoglobinemia (blood disorder) upon acute or repeated exposure; it is also a potential sensitizer and may affect specific organs.
3. Always handle 2-bromo-5-methylbenzenamine in a certified fume hood or with adequate local exhaust, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
