How it works
RUO defines the intended context of supply. A material designated Research Use Only is provided for laboratory research and characterized accordingly — by identity and purity — with no representation made about any use beyond that context.
The designation shapes how everything is written. Compound pages describe the molecule and its measurements; they carry no dosing, protocol, or human-use guidance, because those fall outside the RUO frame entirely.
It is a statement about use context, not about quality. A material being RUO says nothing about how pure it is — that is what the certificate reports — only about the terms under which it is supplied.
Why it matters
RUO is what keeps the catalog’s language honest. Characterization describes what a material is; RUO bounds what is claimed about it, and the two together are the whole of what the site asserts.
Because the designation is load-bearing, it is server-rendered and present above the fold on the product, certificate, and science pages — crawlable, not injected, so it cannot be missed or stripped.
It also draws a hard line for content: no efficacy, no therapeutic framing, no use protocols, anywhere. The line is the point.
At Lineará
The Research-Use-Only line appears, server-rendered, on every compound, certificate, and science page — “For Research Use Only · Not for human or veterinary use · Not for diagnostic or therapeutic use.”
The full policy sets out the terms; the designation itself governs how every page is written, from the compound monographs to this glossary.
