An azo dye designed to imitate or approximate the color of cochineal, a red dye originally from insect sources.
From 'azo-' combined with 'cochineal,' itself from Spanish 'cochinilla,' derived from Nahuatl. This represents chemists' attempts to create synthetic replacements for expensive natural dyes in the 1800s.
Azocochineal represents a crucial moment in chemistry history—synthetic azo dyes were so successful at replacing expensive insect-based cochineal red that they nearly destroyed the natural dye trade and freed millions of resources for other purposes.
