(5-Bromo-2-chlorophenyl)(4-ethoxyphenyl)methanone: Characteristics, Structure, and Practical Considerations

What is (5-Bromo-2-chlorophenyl)(4-ethoxyphenyl)methanone?

(5-Bromo-2-chlorophenyl)(4-ethoxyphenyl)methanone shows up in chemical discussions as a member of the benzophenone family. Its formula, C15H12BrClO2, maps out an organic framework mixing bromine, chlorine, and ethoxy substitutions on two aromatic rings bridged by a carbonyl group. Lab reports and chemical catalogs describe this molecule as a crystalline solid under standard conditions. Its appearance often lands in the off-white to pale yellow range, a detail anyone involved in handling needs to know to identify it correctly and spot changes that might indicate impurities or decomposition.

Structure and Properties

This compound’s structure creates a scenario where both rings, one with bromo-chloro substitutions and the other sporting an ethoxy group, influence reactivity and safety. The carbonyl group in the middle makes it more than a passive bystander; this feature enables potential as a building block in pharmaceutical and material synthesis. Density sits around 1.4–1.6 g/cm³. The melting point usually runs between 98°C and 106°C, although variations show up from source to source—this ties to purity and batch history. The solid presents as flakes, powders, or sometimes lumpier forms, but seldom flows as a pearl or liquid unless dissolved. If suspended in a solvent to form a solution, solubility trends toward organic solvents instead of water, due to the molecule's non-polar backbone. Crystal forms tell a lot to anyone working with x-ray diffraction or chemical isolation, often confirming successful synthesis or hinting at problems in a manufacturing run.

Specifications and Handling

In chemical supply, the purity—commonly stated at no less than 98%—carries real consequences for downstream work. Even small contaminants shift reactivity and can put laboratory personnel at risk. The product is shipped and labeled using the HS Code for aromatic ketones, usually under 291439, tying into international customs and transport regulations. The identification and tracking process matters: standards keep labs, shippers, and users speaking the same language across borders. Bulk shipments arrive in airtight containers, protected from moisture and oxidation, since humidity and light start chipping away at stability. Solid material like this calls for careful weighing and slow addition to reaction mixtures, as it releases tiny dust particles that might drift off and add to inhalation risks. Personal experiences underline how the right fume hood, gloves, and mask cut down on exposure, but also how easily dry powders can coat unintended surfaces.

Safety and Hazardous Properties

Not everything about this molecule stays pleasant. Toxicological research signals caution—aromatic ketones with halogen substitutions, much like this one, provoke skin or respiratory irritation. Direct contact can cause allergic responses, and inhaling dust brings risk to airways and lungs. The ethoxyphenyl and halogenated phenyl fragments in its structure hint at persistence in the environment and slow biodegradation, so waste disposal follows strict chemical protocols. Emergency protocols around spills treat this as a hazardous material. I remember a cleanup drill where slow removal, diligent sealing of waste, and thorough documentation traced every grain of powder from bench to waste bin. Long sleeves, goggles, and chemical-resistant gloves become the bare minimum, not just recommendations, in real-world labs or industrial blending rooms handling kilograms of material. Fire safety also becomes an actionable point—halogenated organics can release dangerous gases if heated past their decomposition point or exposed to open flame.

Role as a Raw Material

Industrially, (5-Bromo-2-chlorophenyl)(4-ethoxyphenyl)methanone draws value as a synthetic precursor. Chemical manufacturing routes use it to forge more complex molecules, sometimes in pharmaceuticals, sometimes in specialty polymers or dyes. The core ketone and flexible substitution pattern enable selective modifications—chemists leverage this to design new biologically active compounds. In my own work, I have seen new project proposals build from raw materials like this one; success often ties to batch reliability, transparent specifications, and responsive suppliers. Without dependable raw material sourcing, research gets bogged down, and timelines creep. The chemist’s relationship with their suppliers moves past transactional—the bottle’s label turns into a story about previous lots, past reactions, near-misses on safety, and the hands-on judgment calls that steer projects clear of hazards.

Reflections and Looking Ahead

Working with (5-Bromo-2-chlorophenyl)(4-ethoxyphenyl)methanone means respecting its strengths and limitations. Chemistry textbooks describe the facts, but spending time with these materials in a real lab brings home the importance of planning, mitigation, and openness about risk. The value of clear product information, reliable analytical certificates, and honest conversations with supply chain partners cannot be overstated. For safer workspaces, regular training, documented procedures, and investment in high-quality protective gear deliver more than compliance— they foster a culture where workers look out for each other. Real transformation happens on benches, in storerooms, and during shipments. Tight controls, smart design of experiments, and attention to environmental responsibility keep important chemicals like this from tipping into harm, while unlocking their potential in new discoveries and products.
