High Quality Dichloromethane/DCM/Methylene Chloride Organic Solvent CAS 75-09-2

Industrial-Grade DCM Solvent for Your Manufacturing

CAS 75-09-2 Dichloromethane (DCM) also known as methylene chloride is an organic compound with the chemical formula CH₂Cl₂. It is a colorless transparent liquid with a sweet, ether-like odor. It is slightly soluble in water and miscible with ethanol and ether. DCM is a non-flammable solvent with a low boiling point (39.6–40°C) under normal conditions. At elevated temperatures or in fire conditions, its vapor may decompose to produce toxic gases such as phosgene and hydrogen chloride. DCM solvent is widely used as a lower-flammability alternative to solvents such as petroleum ether and diethyl ether in certain industrial applications.

Dichloromethane/methylene chloride is a versatile industrial solvent widely used for extraction, purification, and cleaning processes in pharmaceutical and chemical manufacturing due to its strong solvency and low flammability.

1. Pharmaceutical Manufacturing

DCM is a key extraction and purification solvent in pharmaceutical production, widely used for:

• Extracting active pharmaceutical ingredients (APIs) from natural sources
• Purifying intermediate compounds via recrystallization
• Serving as a reaction medium for organic synthesis

Historically used in decaffeination processes (though now largely replaced by other methods in most food applications due to regulatory requirements)

2. Chemical Synthesis and Specialty Chemicals

In chemical manufacturing, methylene chloride serves as a reliable reaction solvent due to its chemical stability and excellent ability to dissolve a wide range of reactants. Common uses include:

• Standard organic synthesis reactions
• Production of polymers, resins, and fine chemicals
• Extraction and reaction media in controlled systems
• Agrochemical manufacturing

3. Metal Degreasing and Industrial Cleaning

Dichloromethane possesses strong solvency for oils, greases, and organic contaminants, making it highly effective for vapor degreasing processes on metal parts. Industries relying on this application include:

• Aerospace component manufacturing
• Automotive parts production
• Electronics assembly
• Precision metalworking

Its rapid volatility ensures parts dry quickly without leaving residue, thereby reducing rework and enhancing production efficiency.

4. Paint and Coating Removal

DCM-based formulations effectively penetrate and break down multiple layers of paint, varnish, and coatings. It remains the preferred choice for industrial paint-stripping applications requiring high efficiency and speed.

5. Laboratory Research and Analytical Chemistry

Research laboratories rely on DCM for:

• Liquid-liquid extraction operations
• Preparation of chromatographic mobile phases
• Sample pretreatment for analytical testing
• Routine organic synthesis work

•  Article on DCM applications: Dichloromethane DCM CAS No. 75-09-2 for Industrial Applications

Dichloromethane chemical should be handled in well-ventilated areas using appropriate personal protective equipment and closed systems when possible, and stored in tightly sealed containers in a cool, dry, and ventilated environment away from heat, oxidizing agents, and incompatible materials.

1. Recommended PPE

• Chemical-resistant gloves (nitrile, neoprene, or butyl rubber)
• Safety goggles or face shield
• Protective clothing
• Organic vapor respirator in poorly ventilated areas

2. Engineering Controls

• Use in fume hood or enclosed systems
• Ensure proper ventilation
• Apply vapor recovery systems for large-scale operations

3. Storage Conditions

• Store in tightly sealed containers
• Keep in cool, well-ventilated area (<40°C)
• Avoid oxidizers, strong bases, and reactive metals
• Use secondary containment for spill prevention

4. Spill Response

• Small spills: absorb with inert materials (vermiculite/sand)
• Large spills: evacuate area and follow emergency protocols
• Do not discharge into drainage systems

Q: What is the purity of the dichloromethane (DCM) you provide?

A: Our standard industrial-grade dichloromethane has a purity of at least 99.5%.

Q: Can you provide samples before bulk ordering?

A: Yes, we provide samples for your quality assessment. Please contact us to inquire about sample availability and shipping costs.

Q: What is the minimum order quantity (MOQ)?

A: We do not have a strict MOQ requirement. Whether you need a drum for testing or a full ISO tank for production, we will provide the most cost-effective solution based on your order quantity and delivery location.

Q: How long does delivery take?

A: In-stock products are usually shipped within 3–7 days after order confirmation. Sea freight to most destinations worldwide takes 20–35 days; air freight and express delivery usually take 5–10 days. Please allow extra handling time for the transport of hazardous chemicals requiring special documentation.

Q: Do you provide MSDS/SDS and other technical data?

A: Yes, every order comes with a Safety Data Sheet (SDS), Certificate of Analysis (COA), and Technical Data Sheet (TDS). We can also provide other documents if needed.

Q: Is dichloromethane compatible with plastic containers and pipes?

A: DCM may soften or dissolve some plastics, including PVC, polystyrene (PS), and various rubber materials. It is compatible with polytetrafluoroethylene (PTFE/Teflon), glass, and stainless steel. High-density polyethylene (HDPE) may be suitable for short-term storage under controlled conditions. We recommend that you verify material compatibility for specific applications, especially when gaskets, pipes, and long-term storage containers are involved.

Q: Can methylene chloride be used in food-related fields?

A: It was previously used for decaffeination of coffee and tea, but due to regulatory requirements, modern food processing has largely shifted to alternative methods.
