Useful:

• Chemical Classes: Other Classes -> Sulfur Compounds
• Canonical SMILES: [Na+].[Na+].[SH-]
• Recent ClinicalTrials: Pharmacokinetic Assessment of Sodium Sulfide in Subjects With Impaired Renal Function
• Inhalation Risk: A harmful concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion.
• Synthesis and Application in Silver Nanocube Production: Addition of trace amounts of Na2S or NaHS drastically improves the production rate of silver nanocubes. Sulfide species interact strongly with silver, facilitating the formation of Ag2S nanoparticles.
• Utilization in NOx Reduction: Na2S can effectively reduce NO2 to N2, converting it into nontoxic sodium sulfate (Na2SO4). Also capable of removing SO2 effectively, enabling simultaneous treatment of NOx and SO2 in exhaust gases.
• Chemical Reactions and Applications: Reacts rapidly with di(1-alkynyl) sulfoxides and sulfones to form six-membered heterocyclic compounds. Used in the formation of novel heterocyclic systems.
• Industrial and Chemical Applications: Used in various industries such as pulp and paper, water treatment, textile, and chemical manufacturing.; Water-soluble and creates strongly alkaline solutions, with technical grades exhibiting coloration due to polysulfides.
• Biological Effects and Medical Applications: Na2S and hydrogen sulfide (H2S) have been studied for their anti-inflammatory and anti-apoptotic effects in some studies.; Na2S shown to protect against cardiac ischemia or reperfusion injury by up-regulating antioxidant and detoxification proteins.; Potential role in modulating the expression of Nrf2-dependent antioxidant genes to protect against oxidative stress.
