Morphology
The meaning is directly compositional: 'chemical' (relating to chemistry) modifies 'compound' (a substance formed by chemical combination), so a learner who knows both words can derive that it refers to a substance made by chemical combination. This straightforward adjective+noun construction is cross-linguistically common and follows standard vocabulary composition patterns, making it immediately comprehensible at B1.
Etymology
Chemical compound comes from the simple idea of joining parts: chemical relates to substances and compound means 'made by putting things together'. Think of two different colored building blocks joined to make a new piece, and you have the image behind a chemical compound — a substance where elements join in fixed amounts.
