· ClF

Chlorine monofluoride (ClF) is an interhalogen ceramic compound consisting of chlorine and fluorine atoms in a 1:1 ratio. This material exists primarily as a research compound in solid-state chemistry and materials science, where it is studied for its unique layered crystal structure and potential as a functional ceramic with applications in advanced materials systems. ClF is notable within the interhalogen family for its theoretical low exfoliation energy, suggesting potential for producing few-layer or single-layer structures similar to graphene-family materials.

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.
