Bulk 3-Nitrophthalic Acid Procurement Specs Price Guide
Critical Specifications for 3-Nitrophthalic Acid
When evaluating 3-nitrophthalic acid (CAS: 603-11-2) for industrial applications, procurement managers must look beyond basic purity percentages. This intermediate, also known as 3-nitrobenzene-1, 2-dicarboxylic acid, is critical for pharmaceutical synthesis and dye manufacturing. The physical form is typically an off-white to light yellow powder. However, standard Certificate of Analysis (COA) parameters often omit critical thermal behaviors that impact processing efficiency.
A key non-standard parameter observed in field operations is the thermal sensitivity during drying processes. The literature indicates a melting point around 210 °C with decomposition occurring near 216 °C. In practical bulk handling, this narrow 6-degree window means that aggressive drying protocols intended to reduce moisture content can inadvertently trigger partial thermal degradation. This manifests as a shift in color from off-white to a deeper yellow or tan, which may fail downstream colorimetric specifications for fine chemical synthesis. Operators must ensure drying temperatures remain strictly below the onset of decomposition to maintain the integrity of the o-nitrophthalic acid structure.
The following table outlines the standard technical parameters typically required for industrial procurement. Please note that specific batch values may vary.

Addressing Bulk 3-Nitrophthalic Acid Procurement Specs Price Challenges
Pricing for bulk 3-nitrophthalic acid procurement specs price inquiries is not linear and depends heavily on the required purity grade and packaging configuration. Laboratory-scale pricing often reflects reagent-grade costs, which are significantly higher than industrial manufacturing rates. Procurement strategies must differentiate between synthesis-grade material and standard industrial purity to optimize cost structures.
Volume is a primary driver. Purchasing in metric ton quantities typically reduces the unit cost compared to kilogram-scale orders. However, the manufacturing process used to generate the material also influences cost. Routes that minimize trace impurities, such as residual nitro-isomers or unreacted phthalic anhydride, require more rigorous purification steps, which are reflected in the final price. Buyers should specify their maximum allowable impurity profiles clearly; overly stringent specs on non-critical trace elements can unnecessarily inflate costs.
Physical packaging also impacts the landed cost. For international shipping, we utilize robust physical containment such as 25kg kraft paper bags with PE liners or 500kg IBC totes depending on the order volume. These methods ensure moisture protection during transit without making regulatory claims. NINGBO INNO PHARMCHEM CO.,LTD. focuses on optimizing these logistics parameters to ensure the material arrives within specification, avoiding costs associated with rejected shipments due to moisture uptake or clumping.
Global Sourcing and Quality Assurance
Securing a reliable supply chain for 3-nitro-1, 2-benzenedicarboxylic acid requires vetting suppliers based on production capacity and consistency rather than just spot pricing. Market volatility can affect the availability of raw materials like nitric acid and phthalic anhydride, which upstream impacts the stability of mononitrophthalic acid supply. A qualified global manufacturer should demonstrate the ability to maintain production schedules despite feedstock fluctuations.
Quality assurance extends beyond the initial COA. It involves consistent batch-to-batch reproducibility. For buyers previously sourcing from reagent catalogs, transitioning to bulk industrial supply requires validating that the bulk material meets the same functional performance. We provide comprehensive data to assist in this validation, similar to reference grade equivalent specifications found in technical literature. This ensures that scaling from R&D to production does not introduce variability in the final product yield.
NINGBO INNO PHARMCHEM CO.,LTD. maintains strict internal quality controls to ensure that every shipment meets the agreed-upon commercial terms and technical specs. Our focus is on delivering chemical intermediates that integrate seamlessly into your existing synthesis routes without requiring process re-validation.
Frequently Asked Questions
What is the typical lead time for bulk orders?
Lead times vary based on current inventory levels and production scheduling. Standard ex-stock items may ship within 7-14 days, while custom production runs require a confirmed timeline upon order placement.
Can you provide custom packaging for 3-Nitrophthalic Acid?
Yes, we accommodate specific packaging requirements such as double-lined bags or specific drum configurations to meet your internal handling and storage protocols.
How is purity verified for industrial batches?
Purity is verified using HPLC or titration methods depending on the agreement. Each batch is accompanied by a COA detailing the assay percentage and relevant physical properties.
