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.

Mercuric sulphide red

Controlled Product

CAS: 1344-48-5

Mercuric sulphide red is a chemical compound that belongs to the group of inorganic compounds. It has a phase transition temperature of -42°C, and is soluble in water. Mercuric sulphide red is toxic to humans and animals, and has been shown to cause skin cancer in mice. This compound has been shown to inhibit transcriptional regulation by binding to the polymerase chain reaction (PCR) enzyme, DNA polymerase. Mercuric sulphide red also binds with copper chloride and reacts with ATP, forming an adduct which inhibits the enzyme's ability to synthesize DNA. Mercuric sulphide red can be used as an energy substrate for cells because it undergoes oxidation-reduction reactions with NADH or NADPH. The reaction mechanism for this process is currently unknown but may involve interactions between cysteine residues on the protein and reactive oxygen species.
Mercuric sulphide red is a highly reactive molecule that can bind with many other substances such as
