For any chemical synthesis, a deep understanding of the raw materials' properties is non-negotiable. Thiophene-3,4-dicarboxylic acid (CAS 4282-29-5) is a compound that, while seemingly simple, offers significant utility in various chemical processes. This article delves into its key characteristics, aiding researchers and product formulators in their selection and procurement decisions.

The molecular formula of thiophene-3,4-dicarboxylic acid is C6H4O4S, with a molecular weight of 172.16. Its appearance is consistently described as a white powder, a visual cue for purity and quality. However, beyond the superficial, its true value lies in its precise specifications. High purity levels, typically 99.0% or greater, are crucial for achieving predictable reaction outcomes and ensuring the integrity of the final product, especially when utilized as a pharmaceutical intermediate.

Additional key properties often monitored include loss on drying (≤0.5%), indicating minimal moisture content which can affect reactivity and shelf life. Furthermore, stringent limits on heavy metals (≤10 ppm) and sulphated ash (≤0.2%) are vital for applications where trace impurities can have detrimental effects. These detailed specifications are a hallmark of reliable chemical manufacturers and suppliers.
