Dimethyl Sulfoxide (DMSO) Liquid CAS 67-68-5 — Pharmaceutical & Industrial Grade | UAB An Group Export
Dimethyl Sulfoxide (DMSO) is one of the most scientifically 
fascinating and industrially versatile solvents known to 
chemistry. Unlike almost any other solvent, DMSO is capable 
of penetrating biological membranes — including human skin — 
without causing irreversible structural damage, a property 
that has made it uniquely valuable across pharmaceutical 
drug delivery research, cryobiology, veterinary medicine, 
and laboratory science for over six decades.

First synthesised in 1866 and introduced to biological 
research in the 1960s, DMSO has accumulated an extraordinary 
body of scientific literature documenting its unique 
biological activity, solvent properties, and industrial 
utility. Today it is manufactured globally at high purity 
for use across pharmaceutical, laboratory, industrial, 
and veterinary applications.

UAB An Group Export supplies pharmaceutical and 
industrial-grade DMSO liquid to verified buyers worldwide 
with full documentation and reliable international delivery.

Important Note on Physical State

DMSO has a melting point of 18.5 deg C (65 deg F), meaning 
it may solidify in cool storage or shipping environments. 
This is a normal physical property and does not indicate 
degradation or contamination. Simply warm the container 
gently in warm water (40-50 deg C) to restore the liquid 
state. Product quality is fully maintained through 
solidification and remelting cycles.

Primary Industrial Applications

1. Pharmaceutical Drug Delivery Research
DMSO is the most widely studied solvent for transdermal 
drug delivery, valued for its unique ability to carry 
dissolved active pharmaceutical ingredients (APIs) through 
skin and tissue barriers. This property has driven extensive 
research into topical drug formulations where conventional 
delivery vehicles fail to achieve adequate tissue penetration. 
Pharmaceutical research institutions and drug development 
companies use pharmaceutical-grade DMSO as both a vehicle 
for compound delivery in animal studies and as a standard 
solvent for compound library preparation and biological 
activity screening.

2. Cryobiology and Biobanking
DMSO is the gold standard cryoprotectant in cell and tissue 
preservation for biobanking, stem cell therapy, reproductive 
medicine, and blood banking. At concentrations of 5-10% 
v/v in cryopreservation media, DMSO prevents the formation 
of ice crystals that would otherwise destroy cellular 
structures during freezing to cryogenic temperatures. It 
is used in the preservation of red blood cells, platelets, 
bone marrow, embryos, oocytes, and a wide range of primary 
cell types and cell lines.

3. Laboratory Solvent and Compound Storage
DMSO is the preferred solvent for dissolving and storing 
compound libraries in pharmaceutical and biochemical 
research, valued for its ability to solubilise both 
polar and non-polar compounds at high concentrations. 
Its low freezing point (when mixed with water) and 
excellent long-term compound stability make it the 
standard vehicle for high-throughput screening (HTS) 
compound collections. Most pharmaceutical compound 
libraries worldwide are stored as DMSO solutions.

4. Industrial Chemical Processing
In industrial chemistry, DMSO serves as a high-performance 
reaction solvent for specialty chemical synthesis, polymer 
processing, and extraction operations. Its exceptional 
solvency for both polar and non-polar compounds makes 
it valuable in processes where conventional solvents 
cannot achieve the required dissolution or reaction 
conditions. It is also used as a reaction solvent in 
the synthesis of pharmaceuticals, agrochemicals, and 
specialty chemical intermediates.

5. Veterinary Medicine
DMSO has regulatory approval as a veterinary pharmaceutical 
in several jurisdictions, used as a topical anti-inflammatory 
agent and carrier for veterinary drug formulations. Its 
membrane penetration properties make it effective for 
delivering anti-inflammatory active ingredients to 
musculoskeletal tissues in horses and other large animals.

6. Electronics and Specialty Cleaning
In electronics manufacturing, DMSO is used as a specialty 
cleaning solvent for removing photoresists, polymer films, 
and specialty coatings from electronic components and 
semiconductor wafers where conventional cleaning solvents 
are insufficient.

Handling and Safety

CRITICAL: DMSO readily penetrates skin and can carry 
dissolved substances through the skin barrier. Always 
ensure hands and skin are clean and free of any other 
chemical before handling DMSO. Use clean nitrile gloves 
specifically for DMSO handling. Eye protection is 
mandatory. Handle in a well-ventilated area. Do not 
handle DMSO while wearing contaminated gloves from 
other chemical handling operations.

Storage Requirements

Store at 15-30 deg C in tightly sealed glass or HDPE 
containers. Avoid metal containers as DMSO can corrode 
certain metals. Keep away from strong oxidising agents. 
Protect from moisture absorption — DMSO is hygroscopic 
and will absorb water from the atmosphere if left 
unsealed. Ideal storage temperature range: 20-25 deg C 
to maintain liquid state.
