For chemists and researchers involved in organic synthesis, a deep understanding of the properties of key intermediates is fundamental to designing efficient and successful reaction pathways. 5-tert-Butyl-2-hydroxybenzaldehyde (CAS 2725-53-3) is an aromatic aldehyde whose chemical characteristics make it a valuable tool in numerous synthetic endeavors.

Chemically, 5-tert-Butyl-2-hydroxybenzaldehyde has the molecular formula C11H14O2 and a molecular weight of approximately 178.23 g/mol. Its structure features a benzene ring substituted with a hydroxyl group (-OH) at the ortho position and an aldehyde group (-CHO) at the para position relative to the hydroxyl. A bulky tert-butyl group (-C(CH3)3) is located at the meta position to the aldehyde and para to the hydroxyl group. This specific arrangement influences its reactivity and physical properties.

Typically, this compound appears as a colorless to light yellow powder or liquid, depending on its purity and ambient temperature. Its melting point is often cited in the range of 100-103 °C, indicating it's a solid at standard room temperature. The presence of the hydroxyl group allows it to form hydrogen bonds, affecting its solubility and boiling point (around 251-252 °C at 760 mmHg). The aldehyde functionality is susceptible to oxidation and nucleophilic addition reactions, making it a versatile intermediate.

When considering where to buy 5-tert-Butyl-2-hydroxybenzaldehyde, understanding these technical details helps in selecting the right grade. For synthesis where precision is key, such as in pharmaceutical intermediate production, purchasing from a reputable supplier that clearly specifies purity (e.g., ≥97%) and provides detailed technical data is essential. Exploring options from manufacturers that offer competitive CAS 2725-53-3 pricing for bulk orders can also be advantageous.

In summary, familiarizing oneself with the structural and chemical properties of 5-tert-Butyl-2-hydroxybenzaldehyde is crucial for its effective utilization in synthesis. This knowledge empowers researchers and procurement specialists to make informed decisions when sourcing this important chemical intermediate from reliable manufacturers.
