The solution is typically yellow to dark green and has a rotten-egg odor due to the Hydrogen Sulfide (H2S) content. The product strength ranges from 20% to 45% by weight and weighs 9 to 11 pounds per gallon (specific gravity from 1.13 to 1.30 g/cm3). Solutions of NaHS are considered stable in normal transportation. The vapor space over NaHS solutions contains highly toxic Hydrogen Sulfide gas. The Hydrogen Sulfide gas is colorless and it is heavier than air. It will remain close to the ground and collect in low lying areas. The amount of Hydrogen Sulfide gas evolved from NaHS solutions is noticeably increased when the pH of the solution is below the pH of 10.2. This happens when the solution comes into contact with acidic materials or other materials that have a pH lower than 10.2. Dilution of the material will also create a minimal amount of Hydrogen Sulfide gas due to the lower pH of water coming in contact with the solution.

These observations have generated interest in harnessing H2S as a potential therapeutic agent to treat disease states and chronic conditions associated with H2S-based signaling. A mechanistic analysis of these physiological processes reveals the prevalence of H2S and other reactive sulfur species including sulfane sulfur and persulfides. To better understand the biological properties of these reactive sulfur species, chemical tools which provide methods of generating these fleeting species under controlled reaction conditions are needed.

Abstract: Plant secondary metabolites (SMs) play important roles in plant survival and in creating ecological connections between other species. In addition to providing a variety of valuable natural products, secondary metabolites help protect plants against pathogenic attacks and environmental stresses. Given their sessile nature, plants must protect themselves from such situations through ac- cumulation of these bioactive compounds. Indeed, secondary metabolites act as herbivore deterrents, barriers against pathogen invasion, and mitigators of oxidative stress. The accumulation of SMs Citation: Jan, R.; Asaf, S.; Numan, are highly dependent on environmental factors such as light, temperature, soil water, soil fertility, M.; Lubna; Kim, K.-M. Plant and salinity. For most plants, a change in an individual environmental factor can alter the content Secondary Metabolite Biosynthesis of secondary metabolites even if other factors remain constant.
