Morphology
The literal composition 'research' (investigation) + 'chemical' (a substance) transparently yields 'a chemical used for research', which a B1 learner who knows both words can infer. However, the common colloquial sense—a euphemistic label for designer or psychoactive drugs sold as 'research chemicals'—is a specialized, culture-bound meaning not predictable from the parts, so the item is only partially transparent.
Etymology
Research chemical comes from the simple idea of a chemical made for research in a lab, often man-made so scientists can study its effects. That's why it means 'a man-made substance created mainly for scientific study and often not approved for medical use'.
