What Is Isopropyl 2-Bromo-2-Methylpropanoate?

Isopropyl 2-Bromo-2-Methylpropanoate stands out as a chemical compound with clear structure and interesting physical traits. Its formula, C7H13BrO2, reveals a carbon backbone featuring a bromo substituent and isopropyl ester group. Looking at the molecule, you see the influence of halogenation, which leads to a high degree of reactivity compared to most carboxylic esters. Chemists use this compound in atom transfer radical polymerization (ATRP), an industrial synthetic method, to initiate controlled polymer growth. The compound’s molecular weight hits roughly 209.08 g/mol, giving it heft that makes simple handling straightforward for trained professionals. The presence of both bromo- and ester-groups means it bridges organic chemistry’s reactivity and solvency, backing up a reputation for special uses rather than broad, general application.

Physical Properties and Appearance

This compound typically appears as a transparent to pale yellow liquid at room temperature, though under certain temperature and pressure settings, it may solidify into colorless flakes or crystalline granules. Its density registers at about 1.258 g/cm³, a feature that affects storage choices and shipping protocols. Due to a moderate melting point, users may encounter it as a warm, mobile fluid or sometimes as powder if crystallized by cooling. The molecular structure resists water, but dissolves readily in organic solvents like ether, acetone, and dichloromethane. This solubility makes it desirable as an intermediate in synthesis and research. Those handling it must avoid exposure, as it can evaporate easily at room temperature, letting off fumes with a recognizable chemical odor.

Chemical Role and Raw Material Status

Across polymer science, Isopropyl 2-Bromo-2-Methylpropanoate plays a specific role as both a reagent and a building block. Synthesizing specialty polymers or facilitating new radical polymerizations requires a starter compound with both stability and a source of radical reactivity. The bromo group delivers just that, enabling the creation of well-defined polymer chains, which many industries value. This raw material feeds into custom plastics, specialty coatings, and adhesives. The ester group supports reactivity without introducing unnecessary instability, ensuring that scientists and engineers get predictable performance during manufacturing. Its adoption as a raw material in the lab usually means strict control of environment and lots of protective equipment for safe and efficient work.

Specifications Worth Knowing

Practical use demands a focus on technical quality. Purity for Isopropyl 2-Bromo-2-Methylpropanoate usually exceeds 98%, as lower grades risk unwanted side reactions and polymerization problems. The best manufacturers provide detailed specs, including refractive index, boiling and melting points, and sometimes trace impurity levels. Appearance matters too—cloudiness or particulate matter may signal degradation. For storage, recommendations include tightly sealed amber bottles, cool and dry settings, and strict exclusion of moisture. The HS Code for most markets falls under 2915.90, covering halogenated acyclic carboxylic acid derivatives, so importers and customs agencies rely on this designation during shipping and regulatory inspections.

Hazards and Handling

Anybody thinking about using this chemical must weigh risks carefully. Like most brominated organics, contact poses health hazards, including skin and mucous membrane irritation. If vapors escape in an enclosed lab setting, accidental inhalation can trigger coughing, headaches, or other symptoms. Goggles, gloves, and fume hoods make up basic precautions for regular users. The compound may react with strong oxidizers and should remain separated from acids, bases, and open flames. Disposal presents challenges—local and international guidelines demand careful recording and treatment to avoid environmental release. Long-term storage in non-reactive containers limits breakdown and accidental exposure, which helps prevent harmful incidents. For larger facilities, emergency plans focus on spills, fire, and medical exposure, including rapid response kits and specialized cleanup materials.

Why It Matters in Industry and Research

In chemical manufacturing and advanced materials science, no one ignores substances that can jump-start controlled chemical transformations. Isopropyl 2-Bromo-2-Methylpropanoate fills this need, supporting industries chasing durable coatings, efficient adhesives, and custom resins for automotive, electronics, and consumer goods. Research hinges on consistency—batch-to-batch purity saves time and costly troubleshooting. As someone who’s made polymers in the lab, inconsistent starter material leads to cloudy guesses and failed results, so trust in a well-characterized raw material replaces waste with progress. As regulations tighten around hazardous substances, knowing the material’s HS Code, safe handling profile, and storage needs becomes part of daily operations for both researchers and safety officers.
