Description
Propylene Glycol is a USP-grade solvent from Pure Rawz. It’s sold as a laboratory supply for research use.
What is Propylene Glycol?
Propylene glycol is a clear, slightly sweet liquid used as a solvent and humectant. It’s USP grade.
It’s generally recognized as safe in food at low levels.
Mechanism of action
Propylene glycol dissolves both polar and some non-polar compounds and mixes with water. It’s often combined with PEG or ethanol.
It absorbs water from air.
Published Propylene Glycol research
It’s used in pharmaceuticals, cosmetics and food to dissolve compounds and keep them moist.
Labs use it to make liquid research solutions of compounds that don’t dissolve in water.

This listing is a 60ml bottle, priced at $9.27.
Using Propylene Glycol in the lab
Reconstitution liquids and solvents are the part of a protocol that’s easy to overlook. The wrong liquid can stop a peptide dissolving, change its stability or interfere with an assay.
Match the liquid to the compound and to how long you’ll keep the solution. Single-use work can use sterile water, while multi-draw vials need a preservative.
Buy in the size you’ll use before the expiry date. A large bottle that sits open for months isn’t a saving.

- Use: laboratory research only
How to store Propylene Glycol
Keep the bottle sealed in a cool, dark place. Some solvents absorb moisture from the air, so close it after each use. Write the date you opened or mixed it on the label, so anyone else in the lab knows how old it is.
Our reconstitution and solvent range
Different compounds need different liquids. Here’s how our range lines up:
- Bacteriostatic Water: the default for most peptides, with 0.9% benzyl alcohol so a vial can be drawn from for several weeks
- Sterile Water: no preservative, for single-use mixing or assays where benzyl alcohol would interfere
- Acetic Acid Reconstitution Solution: dilute acid for peptides that dissolve poorly in water, such as IGF-1 LR3
- Phosphate Buffered Solution: holds the pH near 7.4 for dilutions and cell work
- L-Glutathione Reconstitution Solution: adds an antioxidant for peptides prone to oxidation
- Reconstitution Solution: a general-purpose sterile diluent for the shelf
- DMSO Dimethyl Sulfoxide: a strong solvent for stock solutions of compounds that won’t dissolve in water
- Benzyl Alcohol USP Grade: preservative and co-solvent for oil-based solutions
- Grape Seed Oil 100% Filtered: a light carrier oil for fat-soluble compounds
Safe handling
Wear gloves and eye protection, work in a ventilated area, and keep flammable solvents away from heat and open flames. Close the bottle after each use.
