1. Phenazine methosulfate CAS 299-11-6 is a yellow crystalline cationic dye, also called PMS and 5-methylphenazinium methyl sulfate, used as an artificial electron acceptor in biochemical assays.
2. Phenazine methosulfate CAS 299-11-6 serves as a redox mediator between reduced coenzymes such as NADH or NADPH and dyes, including tetrazolium salts, or an electrode.
3. Phenazine methosulfate CAS 299-11-6 is employed in dye-linked assays of dehydrogenases, including glucose-6-phosphate dehydrogenase, lactate dehydrogenase, succinate dehydrogenase, and methanol dehydrogenase.
4. Phenazine methosulfate CAS 299-11-6 is used in histochemistry and diagnostic enzyme work, and it is more light-sensitive than phenazine ethosulfate or 1-methoxy-PMS.

1. Phenazine methosulfate CAS 299-11-6 should be stored at about −20°C in a tightly closed container, protected from light, in a dry and well-ventilated place.
2. Phenazine methosulfate CAS 299-11-6 should be kept away from strong oxidizing agents, and solutions should be made fresh and kept dark because light can demethylate it to phenazine and formaldehyde.
3. Phenazine methosulfate CAS 299-11-6 has no single published powder shelf life on the laboratory safety data sheets reviewed, so the batch label should be followed.

1. Phenazine methosulfate CAS 299-11-6 causes skin irritation (H315) and serious eye irritation (H319).
2. Phenazine methosulfate CAS 299-11-6 may cause respiratory irritation (H335).
