· JVASP-12762· PaCl5

PaCl₅ (protactinium pentachloride) is a rare ceramic compound composed of the actinide element protactinium in its +5 oxidation state. This material exists primarily in laboratory and research contexts rather than commercial production, as protactinium is a scarce synthetic element with limited availability and significant radiotoxicity. The compound is of interest in nuclear chemistry and materials science research for understanding actinide chemistry, solid-state physics of highly unusual ceramic phases, and potential applications in advanced nuclear fuel cycles or specialized catalyst development.

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.
