What is 90% dimethyl sulfoxide (DMSO)?
CAS 67-68-5 DMSO 90% refers to a solution where 90% of the liquid is the powerful organic solvent Dimethyl Sulfoxide (CAS 67-68-5), and the remaining 10% is almost always purified water.
What is CAS 67-68-5 DMSO 90% used for?
| Most Common Applications | • Cryopreservation: DMSO 90% is used for freezing and preserving many types of mammalian cells (e.g., stem cells). • Laboratory Reagent: Used as a solvent for biological assays where pure DMSO is too harsh. • Topical Formulations: A common base strength for some veterinary or research-grade topical preparations. |
| Critical Distinction | Not for human pharmaceutical use unless specially formulated and certified. While safer than pure DMSO, "90%" is a concentration, not a purity grade. It must be prepared from a high-purity DMSO source (e.g., USP grade) for medical applications. |
