Fine Chemicals · Dyes · Intermediates · Feed Additives
Jiangsu Shangyang Chemical New Materials Co., Ltd. focuses on fine chemicals, supplying quinophthalone yellow dyes (Solvent Yellow 114, Disperse Yellow 54) and anthraquinone blue solvent dyes (Solvent Blue 35/36), together with key intermediates such as 3-Hydroxyquinaldine-4-carboxylic acid and Isatin, plus feed-grade folic acid — serving plastics coloring, fiber dyeing, printing inks and animal nutrition.
PRODUCTS
Four series cover quinophthalone yellow dyes, anthraquinone blue solvent dyes, dye intermediates and feed additives — offering both solvent and disperse dye systems with matched intermediates.
Product system note: The quinophthalone yellow series (Solvent Yellow 114 / Disperse Yellow 54, CAS 7576-65-0, C18H11NO3) and the anthraquinone blue series (Solvent Blue 35/36) form two major solvent dye families, supported by key intermediates such as 3-Hydroxyquinaldine-4-carboxylic acid and Isatin, extending to feed-grade folic acid and other nutritional additives.

APPLICATIONS
Our dye series deliver excellent heat, light and migration resistance; intermediates and feed additives serve downstream synthesis and livestock industries.
Suitable for PS, HIPS, ABS, PC, PMMA, AS, PET, RPVC, SAN and other commodity and engineering plastics — stable colors and no migration under high-temperature molding.
For HT-HP dyeing, carrier dyeing and printing of polyester fibers — good levelness, lightfastness up to grade 6–7.
For printing inks, heat-transfer inks and inkjet inks — brilliant shades, high tinctorial strength, compatible with high-speed printing.
For coloring secondary acetate and triacetate fibers; combinable with disperse blues for olive, grey, brown and other compound shades.
Intermediates such as 3-Hydroxyquinaldine-4-carboxylic acid and Isatin are used in quinophthalone/anthraquinone dye and pharmaceutical synthesis, providing a stable raw-material supply for downstream dye production.
Feed-grade folic acid (Vitamin B9) is used in poultry, swine, ruminant and aquaculture feed to support red blood cell formation, reproduction and growth.
ABOUT
Focused on fine chemical dyes, we serve downstream manufacturers with consistent quality and professional technical support.
The company is rooted in chemical new materials and fine chemicals, supplying solvent dyes, disperse dyes, dye intermediates and feed additives widely used in plastics, synthetic fibers, inks, pharmaceutical chemistry and animal nutrition — with end-to-end support from product selection and color matching to process adaptation.
Our portfolio is built around two core solvent dye families — quinophthalone yellows (Solvent Yellow 114, Disperse Yellow 54) and anthraquinone blues (Solvent Blue 35/36) — supported upstream by key intermediates such as 3-Hydroxyquinaldine-4-carboxylic acid and Isatin, and extended downstream to feed-grade folic acid and other nutritional additives. This end-to-end chain from intermediates to finished dyes and application support helps customers streamline sourcing and secure supply stability.
Every batch undergoes strict outgoing inspection with recorded quality data and batch-by-batch verification of key parameters. We also provide technical support covering selection advice, color matching and process adaptation, and respond quickly to inquiries and sample requests to help customers shorten development and trial-production cycles.
