Chemical Identity and Structure

1-(2-Methoxyphenyl)propan-2-ol (CAS to be verified; SKU P698153) belongs to the class of benzylic secondary alcohols. Its structure consists of a propan-2-ol chain appended at the 1-position to a phenyl ring that carries a methoxy group at the ortho (2-) position. This ortho-methoxy motif is chemically reminiscent of the guaiacol scaffold, which appears widely in natural products, pharmaceuticals, and flavor chemistry.

The compound possesses one stereogenic carbon at C-2 of the propanol chain, giving rise to R and S enantiomers. Researchers requiring enantiopure material should confirm the optical specification with Aladdin Scientific at the time of ordering, as racemic and enantioenriched forms may be available. The molecular formula is C₁₀H₁₄O₂ with a molecular weight of approximately 166.22 g/mol.

Physicochemical Properties and Stability

As a secondary benzylic alcohol, 1-(2-Methoxyphenyl)propan-2-ol is expected to be a colorless to pale-yellow liquid or low-melting solid at ambient temperature; the exact physical state should be confirmed from the product's Certificate of Analysis (CoA). The hydroxyl group confers moderate water miscibility and the ability to form hydrogen bonds, while the aromatic methoxy group increases lipophilicity relative to unsubstituted phenylpropanols.

The compound is generally stable under standard laboratory conditions. However, benzylic alcohols can undergo oxidation in the presence of strong oxidizing agents, and prolonged exposure to air or light may promote gradual degradation. The ortho-methoxy group may also participate in intramolecular interactions that influence reactivity under acidic conditions. It is advisable to store the reagent under an inert atmosphere (nitrogen or argon) if long-term storage is required.

Laboratory Applications and Synthetic Utility

1-(2-Methoxyphenyl)propan-2-ol serves as a versatile intermediate in organic synthesis. Its benzylic hydroxyl group can be functionalized via oxidation to give the corresponding ketone (1-(2-methoxyphenyl)propan-2-one), or converted to a leaving group for nucleophilic substitution reactions. The secondary alcohol is also amenable to esterification, etherification, and Mitsunobu reactions, enabling access to a range of structurally diverse derivatives.

The compound's structural similarity to biologically relevant arylpropanolamine and phenylpropanolamine scaffolds makes it relevant to medicinal chemistry programs exploring adrenergic, dopaminergic, or related pharmacological targets. In asymmetric synthesis, enantiopure forms of this alcohol can serve as chiral auxiliaries or as substrates for kinetic resolution studies. Additionally, the guaiacol-like aromatic system is of interest in flavor, fragrance, and natural-product total synthesis research.

Safe Handling, Storage, and Disposal

Personal Protective Equipment (PPE): When working with 1-(2-Methoxyphenyl)propan-2-ol, wear appropriate PPE including chemical-resistant gloves (nitrile recommended), safety goggles, and a laboratory coat. Work in a well-ventilated fume hood to minimize inhalation of vapors.

Storage: Store the reagent in a tightly sealed container in a cool (2–25 °C recommended; confirm with CoA), dry, and well-ventilated area, away from heat sources, open flames, and incompatible materials such as strong oxidizers and strong acids. Keep away from direct sunlight.

Spill and Disposal: In the event of a spill, absorb with an inert material (e.g., vermiculite or dry sand) and collect in a suitable container for disposal. Dispose of all waste in accordance with local, regional, and national regulations. Do not pour down the drain without checking local wastewater regulations.
