Yixing Xinyu Chemicals Co., Ltd.

Yixing Xinyu Chemicals Co., Ltd. is based in China and lists six active products in its catalogue. The company classifies its offerings under Laboratory Chemicals, Chemicals & Allied Products, Cosmetic Chemicals and Laboratory Reagents. The listed items include several sulfonated aromatic amines such as 2,5‑diaminotoluene sulfate and P‑phenylenediamine, as well as hydroxy‑ethyl substituted derivatives. Each product is identified by its chemical name only, without additional specifications or HS‑code data in the source information. The supplier is recorded as an imported tier with a harbor trust rating, indicating it operates through international trade channels.

The catalogue focuses on specialty organic intermediates used in dye‑intermediate synthesis, hair‑color formulations and analytical reagents. All six chemicals are supplied in sulfate or dihydrochloride salt forms, which are common for improving water solubility in laboratory applications. No explicit purity grades, packaging sizes or regulatory certifications are provided in the source facts. The product set reflects a niche segment of aromatic amine chemistry that serves both industrial and research markets.

The product list comprises aromatic diamine sulfates and related hydroxy‑ethyl derivatives, which are typical intermediates for azo‑dye production, polymer stabilization and cosmetic formulation. In the broader market, such chemicals are offered in purity grades ranging from 95 % to technical grade 99 %, with analytical certificates specifying water content, heavy‑metal limits and melt point. Buyers often encounter variants with alternative counter‑ions (e.g., chloride, nitrate) and may request bulk quantities packed in HDPE drums or IBC totes.

Industry standards for these categories include compliance with REACH registration in the EU, FDA‑acceptable purity for cosmetic use, and ISO 9001‑based quality management for bulk chemical suppliers. Typical specifications cite a minimum of 98 % assay by HPLC, moisture below 0.5 % and absence of known carcinogenic impurities such as 4‑aminobiphenyl.
