Definition

Noun: A blue dye obtained from plants or made synthetically. It is the primary coloring component of natural indigo.

Usage

Indigotin is a technical term used primarily in chemistry, dyeing, and textile manufacturing. It refers to the specific chemical compound that gives indigo its characteristic blue color.

Examples

• The traditional method of extracting indigotin from the plant is a complex chemical process.
• Synthetic indigotin, first produced in the late 19th century, revolutionized the textile industry.
• The purity of the blue color in these jeans is due to the high concentration of indigotin in the dye.

Advanced Usage

• Chemical Context: In scientific literature, is often discussed in relation to its molecular structure (C₁₆H₁₀N₂O₂), its reduction and oxidation states during the dyeing vat process, and its isomers.
• Historical/Artisanal Context: The term may be used when discussing the history of dyes, comparing the properties of natural plant-derived indigotin versus its synthetic counterpart.

Variants and Related Words

• Indigo: The common name for the dye or color. While often refers to the dye mixture or the color itself, specifies the pure chemical compound.
• Indican: A colorless precursor compound found in indigo plants that is hydrolyzed to form indigotin.

Synonyms

• Indigo blue (when referring specifically to the colorant compound)
• CI 73000 (its Colour Index generic name)

Notes

Indigotin is not typically used in everyday language. In most general contexts, the word indigo is sufficient. Indigotin is precise terminology for scientific, industrial, or detailed historical discussions about the dye's composition.
