Acid yellow 23

Acid Yellow 23 is a synthetic acid dye with molecular formula C16H12N4O9S2·3Na, supplied by Tianjin Jahe Science & Technology Co., Ltd from their facility in Tianjin, China. The product is described in the source as a reddish-violet powder with a stated strength of 200.0%, indicating a concentrated preparation relative to a standardised colour value. It exhibits high water solubility at 5.0% concentration, which facilitates preparation of stock solutions for continuous and batch dyeing processes.

The dye's chemical structure features two sulfonate groups and three sodium counterions, classifying it as a monoazo acid dye with strong anionic character. This structure provides affinity for protein fibres such as wool and silk, and for cationic-modified synthetic substrates. A strength of 200% implies the commercial product contains additional standardising agents or buffer salts to adjust colour yield, which is common practice for ensuring reproducible application. The stated compatibility with textiles, paper, and plastics indicates versatility across pH-sensitive and non-textile coloration applications.

Industrial users employ Acid Yellow 23 in textile printing and dyeing, paper colouration, and selected plastic masterbatch applications where regulatory compliance permits. The food-contact suitability is not stated and should not be assumed. Buyers should confirm minimum order quantities, lead times, and available Incoterms directly with Tianjin Jahe, as these operational details are not substantiated in the source data. The supplier maintains harbour trust tier status with no recorded response metrics, suggesting the need for proactive communication planning.
