Understanding the Properties and Safety of 5-Bromovanillin
5-Bromovanillin, identified by its CAS number 2973-76-4, is a chemical compound with distinct physical and chemical properties that dictate its handling and applications. Typically appearing as a light yellow to off-white powder, its physical form is consistent with many fine chemical intermediates. Its molecular formula is C8H7BrO3, with a molecular weight of 231.04 g/mol. This structure endows it with specific reactivity characteristics that are leveraged in various synthesis pathways.
One of the key physical parameters for 5-Bromovanillin is its melting point, which is consistently reported in the range of 164-166°C. This relatively high melting point indicates a stable solid form under standard ambient conditions. Chemically, it is described as stable under normal storage and handling conditions, provided it is kept in tightly closed containers in a cool, dry, and well-ventilated area, away from incompatible substances. Sensitivity to air and light is also noted, suggesting that proper storage, often in dark, inert conditions, is beneficial for maintaining its integrity over time.
From a safety perspective, 5-Bromovanillin is classified as an irritant. Hazard statements such as H315 (causes skin irritation), H319 (causes serious eye irritation), and H335 (may cause respiratory irritation) are commonly associated with this compound. Consequently, appropriate precautionary statements must be followed during handling. These include wearing protective gloves, eye protection, and suitable respiratory protection, especially when working with the powder form. Good laboratory practices, such as working in a well-ventilated fume hood, are essential to minimize exposure.
In terms of regulatory classification, its HS code is often listed as 2913000090, and it is assigned a WGK Germany rating of 3, indicating a high degree of hazard in water. Understanding these properties and safety guidelines is crucial for any laboratory or manufacturing facility that utilizes 5-Bromovanillin. Reliable suppliers, particularly from regions like China, provide comprehensive Material Safety Data Sheets (MSDS) that detail all these aspects, ensuring users can handle the substance safely and effectively.
