Pharmaceutical Grade DMSO
Controlled Quality for Sensitive Applications
Product Overview
Our Pharmaceutical Grade DMSO provides tighter control of selected quality parameters compared with the industrial specification.
Important: This grade designation describes a supply specification. It does not by itself establish compliance with USP, Ph. Eur., ChP or GMP requirements, or suitability for direct pharmaceutical use. Any required compliance status and supporting documentation must be confirmed for the specific product and intended application before purchase.
Pharmaceutical Grade DMSO — Type II
Controlled UV, Residue and Purity for Sensitive Applications
Not all DMSO applications require the same specification.
We help you choose the specification that fits your process — not simply the highest grade available.
