The phrase is fully compositional: 'research chemical' denotes a chemical used for research and 'unregulated' means lacking oversight, so the combined meaning is directly derivable as a chemical used in research that is not controlled by regulators. This adjective+noun+noun pattern is transparent and common across languages, so a B1 learner who knows the constituents should understand it.
Etymology
Unregulated research chemical paints a simple picture: a bottle in a lab labelled research chemical but with no rules because it is unregulated, which means 'not checked' by authorities. That's why the phrase means a chemical made for study that is not controlled or watched and so can be risky.
