RPH2

Could you clarify what RPH2 refers to? The term could denote multiple things across different fields (for example, a chemical shorthand, a project code, an organization, or a specific acronym in a discipline). If you provide the intended context or full name, I can draft a concise, neutral Wikipedia-style article under 300 words. If you’d like, I can also prepare a disambiguation-style entry that outlines the most common uses of the term.
