C.I. food red 1

C.I. Food Red 1 (CAS 4548-53-2) is a synthetic azo dye also known as CI 14700, 1306 Red, and 12101 Red. It carries no current EU E-code and is classified under HS code 32041200 as a synthetic organic colorant used across food, textile, and paper applications.

In textile and paper dyeing, C.I. Food Red 1 bonds to substrate fibers through ionic interaction with its sulfonate groups, producing stable red shades across a range of pH conditions. In food-adjacent applications, it functions as a colorant to achieve defined red hues in product formulations where permitted by local regulation.

C.I. Food Red 1 is supplied as a crystalline solid and is subject to REACH registration requirements for EU import and use. Buyers should confirm compliance with regional food-contact or textile regulations before procurement. Standard packaging formats and minimum order quantities are available on request.
