What Is (2-Iodo-4-(trifluoromethyl)phenyl)methanol?
(2-Iodo-4-(trifluoromethyl)phenyl)methanol is an aromatic building block featuring three distinct chemical handles on a benzene ring: a primary benzyl alcohol at the 1-position, an iodo substituent at the 2-position (ortho), and a trifluoromethyl group at the 4-position (para). This combination of functional groups makes the compound exceptionally useful in multi-step organic synthesis.
The aryl iodide moiety is one of the most reactive carbon–halogen bonds toward transition-metal-catalyzed cross-coupling reactions, while the –CF3 group imparts metabolic stability, lipophilicity modulation, and strong electron-withdrawing character. The benzyl alcohol group provides a handle for further functionalization, including oxidation to the aldehyde or carboxylic acid, esterification, or conversion to a benzyl halide or ether.
Typical Applications in Research and Synthesis
Cross-Coupling Chemistry: The C–I bond undergoes efficient palladium- or copper-catalyzed coupling reactions including Suzuki–Miyaura (with boronic acids), Sonogashira (with terminal alkynes), Heck, and Buchwald–Hartwig amination reactions. The aryl iodide is generally more reactive than the corresponding aryl bromide or chloride, making it preferable for challenging coupling partners or room-temperature protocols.
Medicinal Chemistry Intermediate: The trifluoromethyl group is a well-established bioisostere frequently incorporated into pharmaceutical candidates to improve metabolic stability and membrane permeability. Compounds bearing both –CF3 and a hydroxymethyl or further-derivatized group are important precursors in drug discovery programs targeting a variety of therapeutic areas.
Directed Metalation and Further Functionalization: The ortho-iodo group can also be utilized in directed ortho-metalation strategies or halogen–metal exchange reactions (e.g., with n-BuLi at low temperature) to generate highly reactive aryllithium species for nucleophilic addition.
Storage, Handling, and Safety Guidance
Storage: (2-Iodo-4-(trifluoromethyl)phenyl)methanol should be stored in a cool, dry, well-ventilated area, away from light, heat, and incompatible materials such as strong oxidizers and strong bases. Sealed storage under inert gas (nitrogen or argon) is recommended to prevent moisture uptake and potential slow oxidation of the benzylic alcohol. Always consult the product-specific Safety Data Sheet (SDS) for exact storage temperature and conditions prior to use.
Handling: Standard laboratory personal protective equipment (PPE) should be worn, including chemical-resistant gloves, safety goggles, and a laboratory coat. Work in a well-ventilated fume hood. Avoid inhalation of dust or vapors and contact with skin or eyes. Wash hands thoroughly after handling.
Disposal: Dispose of according to local, regional, and national regulations for halogenated organic waste. Do not pour down the drain. Consult the SDS for waste disposal recommendations.
Purity, Specification, and Quality Assurance
Aladdin Scientific supplies (2-Iodo-4-(trifluoromethyl)phenyl)methanol (SKU P734948) as a research-grade reagent. For exact purity specifications, available pack sizes, and lot-specific certificate of analysis (CoA) data including NMR, HPLC purity, and melting point, please refer to the product page on the Aladdin Scientific website or contact our technical support team.
When evaluating a reagent of this type for sensitive synthetic applications, researchers should confirm identity by 1H and 19F NMR (the –CF3 group appears as a singlet near –63 ppm in 19F NMR in CDCl3, and the benzylic –CH2OH protons appear as a doublet or singlet in the 4.5–4.8 ppm region in 1H NMR) and purity by HPLC or GC prior to use in critical experiments.

Frequently asked questions
What is the CAS number and molecular formula of (2-Iodo-4-(trifluoromethyl)phenyl)methanol?
The molecular formula of (2-Iodo-4-(trifluoromethyl)phenyl)methanol is C8H6F3IO, corresponding to a molecular weight of approximately 302.03 g/mol. For the confirmed CAS registry number, please refer to the product page for SKU P734948 on the Aladdin Scientific website, as CAS numbers should be verified against the current product listing and certificate of analysis.
Is (2-Iodo-4-(trifluoromethyl)phenyl)methanol suitable for palladium-catalyzed cross-coupling reactions?
Yes. The aryl iodide functionality in this compound makes it an excellent electrophilic coupling partner in palladium-catalyzed reactions such as Suzuki–Miyaura, Sonogashira, Heck, and Negishi couplings. Aryl iodides are generally the most reactive aryl halides in oxidative addition to Pd(0), enabling milder reaction conditions and broader compatibility with sensitive substrates compared to aryl bromides or chlorides.
How should I store (2-Iodo-4-(trifluoromethyl)phenyl)methanol to maintain its integrity?
Store the compound in a tightly sealed container under an inert atmosphere (nitrogen or argon) in a cool, dark, and dry location. Protect from moisture and avoid prolonged exposure to air and light, which can gradually degrade sensitive aryl iodide and benzylic alcohol functionalities. Always consult the product SDS for the recommended storage temperature specific to this lot.
Can the benzyl alcohol group of this compound be selectively oxidized or functionalized independently of the aryl iodide?
Yes, selective manipulation of the benzyl alcohol is achievable under carefully chosen conditions. Mild oxidants such as Dess–Martin periodinane (DMP), Swern oxidation conditions, or MnO2 can oxidize the benzylic alcohol to the corresponding aldehyde without affecting the aryl C–I bond. Esterification or etherification of the alcohol can similarly be performed chemoselectively. The synthetic plan should be designed to account for the reactivity hierarchy of each functional group.
What analytical methods are recommended to verify the identity and purity of (2-Iodo-4-(trifluoromethyl)phenyl)methanol?
Identity is best confirmed by 1H NMR (characteristic benzylic CH2 and aromatic proton signals), 19F NMR (singlet for –CF3 near –63 ppm in CDCl3), and mass spectrometry. Purity is typically assessed by HPLC (reverse-phase, UV detection) or GC. The lot-specific Certificate of Analysis available on the Aladdin Scientific product page provides reference spectral and chromatographic data.
