从China供应商批发进口2-Chlor-4-Aminotoluene-5-Sulfonate Sodium — FOB条款

2-Chlor-4-Aminotoluene-5-Sulfonate Sodium (CAS 130-96-3, molecular formula C7H7ClNNaO3S) is a chlorinated aromatic sulfonate salt supplied by Ningbo Huahui Import&export Co., Ltd. from Zhejiang, China. This compound serves as a critical intermediate in the synthesis of azo dyes and organic pigments, with its chemical structure providing the reactive sites necessary for diazotization and coupling reactions in dye manufacturing. The material is typically supplied as a solid powder with a standard purity suitable for industrial chemical synthesis.

The compound is a derivative of toluene, featuring a chlorine substituent at the 2-position and an amino group at the 4-position, with the sulfonate group at the 5-position enhancing its water solubility. In the chemical industry, it is classified as a specialty intermediate rather than a bulk commodity, with production concentrated in established chemical manufacturing zones like Zhejiang province. Typical specifications for this intermediate include a defined melting point range and controlled particle size distribution to ensure consistent reaction performance in downstream synthesis.

Primary buyers are dye and pigment manufacturers, particularly those producing reactive and direct dyes for the textile sector. The material is also used in the coatings industry for specific pigment formulations. Trade terms for such intermediates from Chinese suppliers typically involve negotiation on minimum order quantities, with packaging usually in fibre drums or HDPE bags to ensure safe handling. Buyers should confirm the exact purity specification, packaging dimensions, and available shipping terms (such as FOB Ningbo) directly with Ningbo Huahui to align with their production requirements.

Ningbo Huahui Import&export Co., Ltd. is a chemical trading company based in Ningbo, Zhejiang, China, with its registered office at 12 F, Jingang Hotel, 51 Yangshan Rd., Ningbo 315000. The supplier is listed on the platform with a 'harbor' trust tier, which indicates a basic level of platform verification.
