Description

1-(2-Hydroxy-5-Methylphenyl)-2-Buten-1-One is a specialized organic compound featuring a phenolic hydroxyl group conjugated with an α,β-unsaturated ketone moiety. This unique structure makes it a valuable intermediate for synthesizing fine chemicals and functional materials where light-absorbing or chelating properties are required. It is primarily sought by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for research and development as well as production-scale applications.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring specific UV-absorbing or metal-binding characteristics.
• Agrochemical Synthesis: Used in the production of advanced crop protection agents and herbicides, leveraging its reactive ketone group for further chemical modifications.
• Organic Light-Emitting Diodes (OLEDs): Serves as a precursor or core structure for electron-transport materials or emissive layer components in display and lighting technologies.
• UV Absorber & Stabilizer Precursor: Acts as an intermediate in manufacturing compounds that protect polymers, coatings, and personal care products from photodegradation.
• Coordination Chemistry & Ligand Synthesis: The phenolic and carbonyl groups provide sites for metal chelation, useful in creating catalysts or metal-organic frameworks (MOFs).
• Fine Chemical & Flavor/Fragrance Intermediate: Employed in the multi-step synthesis of complex aroma chemicals and other high-value specialty organic compounds.

Quality Control

Our production of 1-(2-Hydroxy-5-Methylphenyl)-2-Buten-1-One adheres to stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including HPLC for purity, GC for residual solvents, and spectroscopic identification (IR, NMR). We provide full traceability and Certificates of Analysis (COA) are supplied with each shipment, ensuring compliance with your specific research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
