C.I. pigment yellow 13

C.I. Pigment Yellow 13 (CAS 5102-83-0) is a disazo organic pigment also identified as C.I. 21100, Benzidine Yellow GE, and KI205. It belongs to the diarylide pigment family and is supplied as a nanomaterial-grade solid.

In printing inks, Pigment Yellow 13 delivers strong colour strength and clean greenish-yellow hue through its bis-azo chromophore structure, which absorbs light selectively in the violet-blue range. It is also used in plastics compounding and coatings, where its heat stability and resistance to migration support consistent colour performance across processing temperatures.

Pigment Yellow 13 is available under REACH registration and supplied to European buyers in compliance with applicable nanomaterial notification requirements. Procurement teams should confirm SDS documentation addressing nanomaterial classification prior to ordering. Standard packaging formats vary by supplier; buyers should specify grade and particle size requirements at the time of enquiry.
