Understanding the inherent properties and correct handling of chemical intermediates is crucial for their effective utilization in various industries. 3,4-Dimethylbenzaldehyde (CAS 5973-71-7), a key aromatic aldehyde, is no exception. As a colorless to pale yellow liquid, its physical and chemical characteristics dictate its application scope and storage requirements, influencing its performance in pharmaceutical, agrochemical, and fragrance synthesis.
The molecular formula of 3,4-Dimethylbenzaldehyde is C9H10O, with a molecular weight of 134.18 g/mol. Key physical properties include a boiling point typically between 230-235°C and a density of approximately 1.02-1.04 g/cm³ at 20°C. Its refractive index is around 1.550-1.555 (n²0D). Importantly, 3,4-Dimethylbenzaldehyde is soluble in organic solvents like ethanol and ether but is insoluble in water. This solubility profile is a critical consideration for reaction medium selection and formulation development.
A significant characteristic is its sensitivity to air. This air sensitivity means that optimal storage conditions are essential to maintain its purity and reactivity. Recommendations for storage typically involve keeping the material in a cool, dry place, protected from light, and under an inert atmosphere such as nitrogen. Storage at temperatures between 2-8°C is often advised to minimize degradation and preserve its quality over time. For businesses looking to buy 3,4-dimethylbenzaldehyde, understanding these storage needs upfront helps in planning inventory management and ensuring material integrity upon arrival.
The hazard classification, often including warnings for harmfulness if swallowed and potential skin/eye irritation (e.g., H302-H315-H319), underscores the need for proper handling procedures. Always consult the Safety Data Sheet (SDS) provided by the manufacturer for comprehensive safety information and recommended personal protective equipment (PPE).
When seeking to purchase aromatic aldehydes for industrial use, quality assurance from the supplier is paramount. A reputable 3,4-dimethylbenzaldehyde manufacturer will not only provide high-purity material (≥98% GC) but also offer guidance on proper storage and handling. Working with a reliable 3,4-dimethylbenzaldehyde supplier China can ensure that you receive documentation and support for the product's safe and effective use.
Whether you are synthesizing pharmaceutical intermediates, developing novel agrochemicals, or creating signature fragrances, the fundamental properties and storage of 3,4-Dimethylbenzaldehyde are key to your success. By adhering to recommended practices and sourcing from quality-assured manufacturers, you can leverage the full potential of this vital chemical intermediate.
