Dichloromethane is one of four chlorocarbons that are produced by chlorinating methane. The others that result during this process are chloromethane, trichloromethane (chloroform) and tetrachloromethane (carbon tetrachloride). Dichloromethane is the least toxic of the carbons produced during this process, but it still poses a health risk as it is a highly volatile liquid. The volatility is one of its key properties allowing it to be easily removed.
Dichloromethane (Methylene Chloride) is used in the transportation industry to degrease metal surface for cars, airplane components and railroad tracks. It is also used in organic chemistry labs, in consumer products, and in plastic and acrylic manufacturing.
Dichloromethane (Methylene Chloride), Lab Grade is a liquid solvent with CAS number 75-09-2 and a minimum assay of 99.90%. It’s one of four chlorocarbons made by chlorinating methane, alongside chloromethane, trichloromethane (chloroform) and tetrachloromethane (carbon tetrachloride). It’s a highly volatile liquid, and that volatility is one of its key properties because it lets the solvent be removed easily. Handle it with care, since it still poses a health risk. This page carries a Safety Data Sheet and a Technical Data Sheet, along with Certificates of Analysis. You’ll also find an Allergen Statement, BPA Statement, Manufacturing Process Flow Chart, No Animal Testing Declaration, Non-Irradiation Statement, PFAS/PFOS Free Statement, REACH Compliance Statement and TSE/BSE Declaration.
Dichloromethane works hard across a few different jobs. It degreases metal surfaces on cars, airplane components and railroad tracks. It shows up in organic chemistry labs, consumer products, and plastic and acrylic manufacturing. Foam, varnish and aerosol production are on the list too. Now the real problem. You need the right size, the right paperwork, and a supplier who can actually ship a hazmat solvent. Lab Alley is your guide there. Choose from 500ml bottles up to 55 gallon drums, plus case packs, with the Safety Data Sheet and Certificates of Analysis available right on this page. Pick a size, set up Autoship for repeat orders, or request a quote for larger needs. On budget, on time, every time.

Q: What is Dichloromethane (Methylene Chloride), Lab Grade used for?
A: It’s used to degrease metal surfaces on cars, airplane components and railroad tracks. It’s also used in organic chemistry labs, consumer products, and plastic and acrylic manufacturing, along with foam, varnish and aerosol production.Q: What does Lab Grade mean, and is it suitable for organic chemistry lab work?
A: This product is listed as Lab Grade with a minimum assay of 99.90%. It’s used in organic chemistry labs, but check the Technical Data Sheet and Certificates of Analysis against what your method requires.Q: What sizes are available, and does it ship as hazmat?
A: You can choose 500ml, 1L, 1Gal, 4L, 5Gal and 55Gal, plus cases of 6 x 500ml, 4 x 1L, 4 x 1Gal and 4 x 4L. Yes, it ships as hazmat. The Safety and Shipping tab lists: DOT: Dichloromethane, 6.1, UN1593, PG III.Q: How do I get the SDS and Certificate of Analysis?
A: Open the Product Manuals section on this page for the Safety Data Sheet and Technical Data Sheet. The Certificates of Analysis list sits right beside it, so you can download what you need.Q: How should it be stored?
A: Read our guide on How to Store Dichloromethane and check the Safety Data Sheet before it arrives. Because it’s a highly volatile liquid, it’s worth planning your storage ahead of time.Q: What are the CAS number and assay?
A: The CAS number is 75-09-2, and the assay is a minimum of 99.90%.Q: Can I set up repeat deliveries?
A: Yes. Autoship is available for this product, so you can keep your supply steady without reordering each time.
