· JVASP-143521· Hg5Cl4O4

Hg5Cl4O4 is a mixed-valence mercury chloride oxide ceramic compound containing both mercury(I) and mercury(II) species. This material is primarily encountered in historical chemical research and specialized laboratory contexts rather than mainstream industrial applications, reflecting both its complex synthesis requirements and the regulatory restrictions on mercury-containing materials in modern manufacturing. The compound represents a niche area of inorganic ceramic chemistry, with potential interest in solid-state chemistry studies and specialized electronic or optical research, though practical engineering applications remain limited due to mercury's toxicity and environmental concerns.

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.
