Description

Phosphonic Acid, [2-(2-Methyl-1,3-Dioxolan-2-Yl)-2-Oxoethyl]- (9Ci) is a specialized organophosphorus compound featuring a unique acetal-protected keto phosphonic acid structure. This molecular architecture makes it a valuable versatile synthetic intermediate and functional monomer for advanced material science and pharmaceutical research. It is primarily sought by R&D chemists and process engineers in the fine chemical, agrochemical, and polymer industries for developing novel compounds with tailored properties.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those requiring phosphonate or bisphosphonate moieties for biological activity.
• Agrochemical Synthesis: Used in the research and development of new herbicides, plant growth regulators, and fungicides, where the phosphonic acid group can act as a bioisostere or functional group.
• Ligand and Chelating Agent Precursor: The protected functional groups allow for the controlled synthesis of complexing agents and ligands for catalysis or metal ion sequestration.
• Polymer and Material Science: Acts as a functional monomer for incorporating phosphonate groups into polymers, which can impart flame retardancy, adhesion promotion, or metal-binding properties to coatings and resins.
• Chemical Research & Development: Employed as a versatile synthon in organic synthesis, enabling the introduction of the phosphonic acid functionality under controlled conditions via deprotection of the acetal group.
• Surface Modification Agent: Potential use in creating self-assembled monolayers (SAMs) or modifying surfaces to alter wettability, corrosion resistance, or biocompatibility.

Quality Control

Our production of Phosphonic Acid, [2-(2-Methyl-1,3-Dioxolan-2-Yl)-2-Oxoethyl]- (9Ci) adheres to stringent internal quality standards to ensure batch-to-batch consistency and high purity for research and industrial use. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and potential decomposition. Recommended long-term storage temperature is 2-8°C.
