Chang Zhou Qi Di Chemical Co., Ltd

China hosts the catalogue of Chang Zhou Qi Di Chemical Co., Ltd, which currently lists five distinct chemical products. The active product count of five reflects the company’s focus on benzoic‑acid derivatives and related aromatic chemicals, as shown in its catalogue. The listed items include 2, 3, 4‑trifluorobenzoic acid, 3, 4, 5‑trifluorobenzoic acid, 2‑nitro‑3‑methyl benzoic acid, methyl 2‑nitro‑3‑methyl benzoate, and 2‑nitro‑5‑methyl benzoic acid. Each entry falls under the broader categories of Benzoic Acid and Aromatic Chemicals that are common in organic synthesis applications.

The five products belong to the HS‑code family for organic acids and their derivatives, typically recorded under Chapter 29 (HS 2925). Industry practice for these compounds requires purity levels of 96 %  -  99 % for laboratory or technical grade, with specifications for melting point, water content, and residual solvents. Standard documentation includes a Certificate of Analysis (CoA) and a Material Safety Data Sheet (MSDS). Packaging for bulk shipment is usually in 25 kg polypropylene drums or 5 kg inner bags, compatible with container loads of 20 ft or 40 ft vessels.

The catalogue presents five benzoic‑acid derivatives that are used as intermediates in pharmaceuticals, agro‑chemicals, and polymer additives. 2, 3, 4‑trifluorobenzoic acid and 3, 4, 5‑trifluorobenzoic acid are fluorinated aromatics typically supplied in analytical grade (≥99 % purity) for research and high‑performance material synthesis. Nitro‑methyl benzoic acids and their methyl esters are common in nitration pathways and are usually offered in technical grade (≥96 % purity) with documented melting points between 150 °C and 180 °C. Industry standards such as ISO 9001 quality management and REACH compliance are frequently required for these product types, although the supplier’s own certifications are not listed in the provided facts.
