CAS 1344-48-5
:Mercury sulfide (HgS)
Description:
Mercury sulfide (HgS) is an inorganic compound characterized by its distinct red or black appearance, depending on its crystalline form. It exists primarily in two polymorphic forms: the red form, known as cinnabar, and the black form, known as metacinnabar. Cinnabar is the more stable and commonly encountered form, often found in nature as a mineral. HgS is insoluble in water but can dissolve in strong acids, forming mercury ions. It is notable for its use in various applications, including pigments, where it imparts a vibrant red color, and in traditional medicine, although its use has declined due to toxicity concerns. Mercury sulfide is considered hazardous due to the toxic nature of mercury, which can pose significant health risks upon exposure. As a result, handling HgS requires strict safety precautions to prevent inhalation or ingestion. Its CAS number is 1344-48-5, which is used for identification in chemical databases and regulatory frameworks. Overall, while HgS has historical significance in various industries, its toxicity necessitates careful management.
