5-Chloromethylfurfural/CMF CAS 1623-88-7

1. 5-Chloromethylfurfural is primarily used as a versatile bio-based platform chemical for synthesizing pharmaceuticals, agrochemicals, and renewable polymers, such as polyesters and polyamides.
2. CMF CAS 1623-88-7 serves as a key intermediate in producing 5-hydroxymethylfurfural (HMF) derivatives, furan-based fuels (e.g., dimethylfuran), and other value-added chemicals from biomass.
3. 5-Chloromethylfurfural functions as a precursor for functionalized furan compounds, cross-linking agents, and advanced materials in green chemistry and sustainable industry.

1. Store 5-chloromethylfurfural in a cool, dry, well-ventilated area, protected from light and moisture, in tightly sealed, corrosion-resistant containers under an inert atmosphere (e.g., nitrogen) to prevent hydrolysis and polymerization.
2. Keep CMF CAS 1623-88-7 strictly separate from water, alcohols, strong bases, oxidizing agents, and reactive chemicals to avoid exothermic reactions, chlorine release, or hazardous decomposition.
3. Handle 5-chloromethylfurfural with extreme care using non-sparking tools and grounded equipment; ensure containers are clearly labeled as corrosive and moisture-sensitive.

1. Immediately CMF CAS 1623-88-7 evacuate and isolate the spill area, eliminate all ignition sources, and ensure forced ventilation; avoid any contact with water or moisture during containment.
2. Carefully absorb spilled 5-chloromethylfurfural with dry sand or other inert, non-combustible material; collect into sealed, corrosion-resistant containers for disposal as hazardous waste.
3. Neutralize residual acid with a suitable alkaline material (e.g., sodium bicarbonate) only if trained to do so safely; clean the contaminated surface with a dry method or appropriate solvent, and dispose of all waste according to hazardous material regulations.

1. 5-Chloromethylfurfural is corrosive and causes severe skin burns, eye damage, and respiratory tract irritation upon contact or inhalation of vapors/mists.
2. CMF CAS 1623-88-7 is harmful if swallowed or inhaled, and repeated or prolonged exposure may cause organ damage or sensitization; it may release toxic chlorine gas under certain conditions.
3. Always handle 5-chloromethylfurfural in a certified fume hood or closed system, wearing appropriate PPE including chemical-resistant gloves, face shield, chemical goggles, and protective clothing.
