Description

Formaldehyde Dimer CAS NO 61233-19-0 is a stable, low-molecular-weight oligomer of formaldehyde, offering a convenient and safer-to-handle solid alternative to aqueous formaldehyde solutions. This compound is a crucial chemical intermediate and building block in organic synthesis, valued for its controlled release of formaldehyde under specific conditions. It is essential for manufacturers in the resin, pharmaceutical, and specialty chemical industries seeking precise and efficient cross-linking or methylolation agents.

Application

• Resin Synthesis: A key precursor and cross-linking agent in the production of phenolic resins, urea-formaldehyde resins, and melamine-formaldehyde resins for wood adhesives, laminates, and molding compounds.
• Pharmaceutical Intermediates: Used in the synthesis of various active pharmaceutical ingredients (APIs) and fine chemicals requiring controlled formaldehyde release.
• Chemical Manufacturing: Serves as a methylene donor and intermediate in organic synthesis for agrochemicals, dyes, and specialty polymers.
• Laboratory Reagent: Employed as a stable source of formaldehyde in research and analytical chemistry applications.
• Textile Treatment: Utilized in processes for fabric crease-resistance and durable-press finishing.
• Disinfectant & Biocide Production: Acts as a raw material in the manufacture of slow-release disinfectant and preservative formulations.

Quality Control

Our Formaldehyde Dimer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for industrial and synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is hygroscopic (moisture-sensitive) and should be protected from atmospheric moisture to prevent caking or decomposition.
