· CoAs2

CoAs2 is an intermetallic compound combining cobalt and arsenic, belonging to the family of transition metal pnictides. This material exhibits notable mechanical stiffness and is primarily of research and specialized industrial interest rather than a commodity material. CoAs2 and related cobalt arsenides are investigated for applications in thermoelectric devices, magnetic materials, and high-temperature structural applications, where its density and elastic properties offer potential advantages in niche engineering contexts.

Regulatory Screening

Environmental

Export Control

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.
