4-tert-Butylbenzyl Chloride CAS 19692-45-6

1. 4-tert-Butylbenzyl chloride is primarily used as an alkylating agent and key intermediate in organic synthesis, particularly for introducing the 4-tert-butylbenzyl group into target molecules to produce pharmaceuticals, agrochemicals, and fragrances.
2. 4-tert-Butylbenzyl chloride CAS 19692-45-6 serves as a monomer or building block in the production of specialty polymers, resins, and liquid crystals, where the bulky tert-butyl group enhances thermal stability and modulates physical properties.
3. 4-tert-Butylbenzyl chloride functions as a precursor for synthesizing UV absorbers, antioxidants, and other functional additives for polymer and coating applications.

1. Store 4-tert-butylbenzyl chloride in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed, corrosion-resistant containers under an inert atmosphere (e.g., nitrogen) to prevent hydrolysis and degradation.
2. Keep 4-tert-butylbenzyl chloride CAS 19692-45-6 strictly separate from water, alcohols, bases, oxidizing agents, and reactive chemicals to avoid violent exothermic reactions, gas release (HCl), or hazardous decomposition.
3. Handle 4-tert-butylbenzyl chloride with extreme care using non-sparking tools and grounded equipment; ensure containers are clearly labeled as corrosive, moisture-sensitive, and lachrymatory (tear-inducing).

1. Immediately evacuate and isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; avoid any contact with water or moisture during containment.
2. Carefully absorb spilled 4-tert-butylbenzyl chloride CAS 19692-45-6 with dry sand or other inert, non-combustible material; collect into sealed, corrosion-resistant containers for disposal as hazardous waste.
3. Clean the contaminated surface with a dry method or appropriate solvent under controlled conditions; neutralize residual acid with a suitable alkaline material (e.g., sodium bicarbonate) if trained to do so safely, and dispose of all waste according to hazardous material regulations.

1. 4-tert-Butylbenzyl chloride is corrosive and causes severe skin burns, eye damage, and respiratory tract irritation upon contact or inhalation of vapors/mists; it is a potent lachrymator (causes tearing).
2. 4-tert-Butylbenzyl chloride CAS 19692-45-6 is harmful if swallowed or inhaled, and repeated or prolonged exposure may cause damage to specific organs, including the respiratory system and eyes; it may also cause sensitization.
3. Always handle 4-tert-butylbenzyl chloride in a certified fume hood or closed system, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing; use supplied-air respiratory protection if adequate ventilation is not guaranteed.
