K2HgCl4
ceramic· JVASP-97479· K2HgCl4
K2HgCl4 (potassium tetrachloromercurate) is an inorganic salt compound featuring mercury and chloride ions in a crystalline ceramic structure. This material is primarily encountered in laboratory and analytical chemistry contexts rather than mainstream engineering applications, where it has historically been used as a reagent in chemical analysis and synthesis. Its limited practical engineering use reflects toxicity concerns and the availability of safer analytical alternatives, though it remains relevant in specialized chemistry research and niche applications requiring mercury-based coordination chemistry.

Regulatory Screening
Environmental
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
