Sodium Hydrogen Sulfide (alternatively termed Sodium Hydrosulfide, chemical formula NaHS, CAS No. 16721-80-5) is a highly critical organosulfur precursor and flotation depressant used across the global heavy-industrial spectrum. At Shandong Pulisi Chemical, we specialize in supplying NaHS in high-grade solid flake forms (typically 70% purity) and custom liquid concentrations, engineered specifically to limit hazardous trace impurities like iron, heavy metals, and sodium carbonate.
Industrial synthesis of high-quality NaHS is accomplished primarily through the absorption of hydrogen sulfide gas (H2S) in aqueous sodium hydroxide (NaOH):
Maintaining the precise stoichiometry of this reaction is essential. Any excess of sodium hydroxide results in the undesirable formation of sodium sulfide (Na2S), while insufficient absorption yields unreacted hydrogen sulfide emissions. High-quality NaHS is characterized by low iron concentrations (typically less than 10-15 ppm). Iron impurities can trigger unwanted catalyst poisoning in synthesis reactors and discolor finished goods in leather and textile processing.
Sodium Hydrogen Sulfide serves as a functional reagent across several high-volume industries:
We maintain a rigorous quality assurance framework validated by third-party testing and global compliance registries.
Through continuous investment in regulatory compliance, worker safety, and international quality alignment, Shandong Pulisi Chemical has been recognized with multiple corporate designations:

The logistics of exporting dangerous chemical compounds like Sodium Hydrogen Sulfide (classified under UN 2949 for solid form, and UN 2922 for liquid form) requires adherence to strict safety standards, localized regulatory frameworks, and rapid transit access. Shandong Pulisi Chemical has built a robust supply chain network to address these international demands.
To ensure supply chain resilience, Shandong Pulisi maintains regional product inventories and customized packing units at critical maritime and overland logistics corridors:
Navigating regional regulatory systems is essential for global chemical distribution. Shandong Pulisi holds certifications across major compliance registries:
