Description

Methanediol CAS NO 463-57-0 is the simplest geminal diol, representing the hydrated form of formaldehyde in aqueous solution. This highly reactive intermediate is of significant industrial importance for its role in chemical synthesis and as a key equilibrium component in formaldehyde solutions. It is primarily utilized by manufacturers in the resin, pharmaceutical, and specialty chemical sectors for its ability to act as a versatile building block and methylene source.

Application

• Chemical Synthesis Intermediate: Serves as a crucial precursor and reactive intermediate in the production of various specialty chemicals and fine chemicals.
• Resin Manufacturing: An essential equilibrium component in formaldehyde solutions used to produce urea-formaldehyde, phenol-formaldehyde, and melamine-formaldehyde resins.
• Pharmaceutical Intermediates: Employed in the synthesis of active pharmaceutical ingredients (APIs) and other drug substances requiring methylene bridge formation.
• Biocide and Disinfectant Formulations: Acts as a source of active formaldehyde in controlled-release antimicrobial and preservative systems.
• Textile and Leather Processing: Used in cross-linking agents and finishing chemicals for durable press fabrics and leather tanning auxiliaries.
• Laboratory Reagent: Utilized in research and analytical chemistry as a standard or reagent for specific organic reactions.

Quality Control

Our Methanediol is produced and handled under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and concentration. Certificates of Analysis (COA) documenting key parameters such as assay, water content, and formaldehyde equilibrium are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile nature and equilibrium with formaldehyde, store in a cool, well-ventilated area away from heat sources and incompatible materials. Recommended storage temperature is 2-8°C to maximize stability. Keep container tightly sealed when not in use to prevent evaporation and concentration changes.
