3-(N-Morpholino) propanesulfonic Acid Sodium Salt
Synonym(s): 3-(N-Morpholino)propanesulfonic acid sodium salt, 4-Morpholinepropanesulfonic acid sodium salt, MOPS sodium salt, MOPS, Sodium
Description
MOPS‑Na (3‑(N‑Morpholino)propanesulfonic acid sodium salt) is a high-purity biochemical grade buffering reagent (≥99.0%) designed for rigorous biological and biochemical research applications. This white crystalline salt dissolves readily in water to produce clear, colorless solutions with minimal UV absorbance, making it ideal for experiments requiring high optical clarity and low background interference. With a pKa around 7.2, it offers excellent buffering capacity near physiological pH and maintains stable pH under a variety of experimental conditions — without significantly interacting with metal ions.
