Description

Diethyl Methylenebisphosphonate-P,P'-Dilithium Salt is a high-purity organophosphorus reagent, specifically a dilithium salt derivative of a methylenebisphosphonate ester. This compound is valued for its enhanced stability and solubility in organic synthesis, serving as a versatile building block for complex phosphonate and phosphate-containing molecules. It is primarily utilized by researchers and process chemists in the pharmaceutical, agrochemical, and materials science industries for the development of active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of bisphosphonate drugs for treating bone disorders such as osteoporosis.
• Agrochemical Synthesis: Building block for creating novel herbicides, plant growth regulators, and fungicides with phosphonate moieties.
• Ligand and Catalyst Preparation: Used to prepare chelating ligands for metal catalysis and coordination chemistry.
• Flame Retardant Research: Serves as a monomer or additive in developing phosphorus-based flame-retardant polymers.
• Surface Modification Agent: Employed to functionalize surfaces with phosphonate groups for improved adhesion or corrosion resistance.
• Chemical Biology Probes: Utilized in the design of enzyme inhibitors and molecular probes targeting phosphate-binding sites.

Quality Control

Our Diethyl Methylenebisphosphonate-P,P'-Dilithium Salt is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and ICP-MS, to ensure high chemical purity and consistent performance. Certificates of Analysis (COA) detailing identity, assay, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its hygroscopic and easily oxidized nature, the container must be sealed immediately after use to minimize exposure to moisture and air.
