4, 4-dinitrostilbene-2, 2-disulfonic acid
4,4-Dinitrostilbene-2,2-Disulfonic Acid is an orange powder used primarily as an intermediate in the synthesis of dyes, particularly for textile and leather applications. Its molecular structure, featuring two nitro groups and two sulfonic acid groups on a stilbene backbone, provides reactivity for azo dye formation and water solubility, which is critical for industrial dyeing processes. The compound is supplied with a defined quality index, including minimum content for the active component and limits for impurities.
The material has a molecular formula of C14H10N2O10S2 and a molecular weight of 430 g/mol, with a CAS number of 128-42-7. Its orange appearance is a key identifier, and the binitro acid content is specified at a minimum of 66.0% on a dry basis. The compound also contains controlled levels of binitrobenzyl derivatives (≤0.5%), other organic impurities (≤2.0%), inorganic salts (≤2.0%), and water-insoluble matter (≤1.0%). These specifications ensure consistency in dye synthesis and final product color fastness.
Textile manufacturers and dye producers source this intermediate for its role in creating vibrant, long-lasting colors in fabrics and leather. The compound is typically packed in 25 kg plastic woven bags, which are suitable for bulk handling and storage. Buyers should confirm the supplier’s ability to provide consistent batches, as variations in impurity profiles can affect dye performance. The material’s stability under standard storage conditions makes it a reliable choice for large-scale production.

Sourcing 4,4-Dinitrostilbene-2,2-Disulfonic Acid from Luoyang Hanyi Chemical Co., Ltd - China Import Guide
Before ordering, verify the compound’s quality index, particularly the binitro acid content and impurity levels, as these directly impact dye performance. Request a certificate of analysis from Luoyang Hanyi Chemical Co., Ltd to confirm compliance with your technical specifications. Check for consistency in batch-to-batch data, as variations can affect color fastness and uniformity in downstream applications.
Clarify logistics details, including Incoterms (e.g., FOB Luoyang), lead times, and packaging. The standard packaging is 25 kg plastic woven bags, but confirm whether the supplier can provide alternative options, such as smaller batches or specialized containers for moisture-sensitive environments. Ensure the packaging meets your handling and storage requirements to prevent degradation or contamination.
Quality checks should include visual inspection for color consistency and particle size, as well as analytical testing for purity and impurity profiles. For critical applications, consider third-party inspection or testing upon arrival. Request documentation such as the MSDS and handling guidelines to ensure safe processing and storage. If the compound will be used in regulated industries, confirm whether the supplier provides additional compliance certifications or regulatory support.
