Description

2-Hydroxymethyl-15-Crown-5 is a functionalized crown ether derivative, specifically a 15-membered macrocyclic polyether with a hydroxymethyl pendant group. This structure is critical for its ability to selectively bind and transport alkali metal cations, particularly potassium and sodium ions, with high efficiency. It is an essential building block and complexing agent for researchers and manufacturers in advanced material science and chemical synthesis. Key industries that utilize this compound include pharmaceuticals, chemical sensors, and separation technologies.

Application

• Phase-Transfer Catalyst: Facilitates reactions between reagents in immiscible phases, particularly useful in organic synthesis and polymer chemistry.
• Ionophore for Chemical Sensors: Serves as a key selective component in ion-selective electrodes (ISEs) and optodes for detecting potassium and sodium ions in analytical and clinical settings.
• Metal Ion Extraction & Separation: Used in liquid-liquid extraction processes to selectively separate and recover specific alkali metals from complex mixtures or waste streams.
• Pharmaceutical Intermediate: Acts as a complexing agent or a functional precursor in the synthesis of specialized drug delivery systems and active pharmaceutical ingredients (APIs).
• Polymer Modification: The hydroxymethyl group allows for covalent attachment to polymer backbones, creating crown ether-functionalized materials for membranes or resins.
• Academic & Industrial Research: A fundamental reagent for studying host-guest chemistry, supramolecular assembly, and cation transport mechanisms.

Quality Control

Our 2-Hydroxymethyl-15-Crown-5 is produced under a strict quality management system to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and purity and spectroscopic identification (IR, NMR). A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product performance. Keep away from incompatible materials.
