phosphinic
Definition
- Adjective:
- Relating to phosphinic acid: "Phosphinic" is an adjective used in chemistry to describe compounds or derivatives related to phosphinic acid, which is an oxyacid of phosphorus with the formula H₃PO₂ (or more accurately, H₂P(O)OH).
- Pertaining to a specific phosphorus oxidation state: It indicates the presence of phosphorus in the +1 oxidation state within a molecular structure, typically in organic or inorganic chemistry contexts.
Usage Examples
