Product Parameters
Bromoethane (Ethyl bromide) – CAS 74-96-4, formula C₂H₅Br, MW 108.97. A volatile, colourless, short-chain aliphatic bromoalkane prized for its small size and high reactivity. It serves as a powerful ethylating agent, introducing an ethyl group under mild conditions and acting as a key building block for fine chemicals.
Specifications & Quality Control
We supply bromoethane in two purity tiers: standard grade ≥99.0 % and pharma grade ≥99.5 % (both by GC). Each lot is purified by multi-plate distillation to guarantee low moisture, low acid value and minimal non-volatile residues. Continuous GC monitoring ensures batch-to-batch consistency, supporting seamless scale-up from gram-level R&D to multi-ton production.
Main Applications
Bromoethane is a versatile, high-value intermediate.
Pharma & Agro-chemicals: ethylates APIs (sedatives, antibiotics) and pesticide technicals.
Fine & Specialty Chemicals: builds dyes, fragrances, surfactants and LC-material precursors.
Organic Synthesis & R&D: routine reagent for Grignard and alkylation protocols in universities, institutes and corporate labs.
Use, Storage & Safety Guidelines
Store in a cool, well-ventilated area away from strong oxidisers and bases. Keep containers tightly closed and light-protected. Operators must wear compatible gloves, goggles and, if vapour may be generated, a respirator; prevent inhalation and skin contact. Refer to MSDS for full data.
Packaging, Logistics & Technical Services
We offer flexible packaging solutions: industrial-grade products in 250 kg drums, plus laboratory sizes of 100 ml and 500 ml reagent bottles. Each shipment is accompanied by a Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS), and third-party test reports can be provided on request. A dedicated technical-support team is available for application advice, process optimization, and any other assistance you may need.
