DMSO-ACS Spectrophotometric Grade

DMSO-ACS Spectrophotometric Grade
Dimethyl Sulfoxide-ACS Spectrophotometric Grade
Dimethyl Sulfoxide (DMSO) ACS Spectrophotometric Grade meets the American Chemical Society’s (ACS) 9th Edition Specifications for Reagent Chemicals.
In addition to the standard purity requirements, this grade features strict limits on UV absorbance at five specified wavelengths, ensuring exceptional analytical clarity. It is the preferred solvent for UV spectrophotometric applications where minimal background absorbance is critical.
