Drop-In Replacement For Us-Cato C4X-18147: Bulk Sourcing
Technical Specifications and Purity Grades for 2-Chloro-N-methyl-N-(4-nitrophenyl)acetamide (CAS 2653-16-9) as a Drop-in Replacement
For procurement managers and QC directors evaluating a drop-in replacement for US-CATO C4X-18147, the primary concern is whether 2-Chloro-N-methyl-N-(4-nitrophenyl)acetamide (CAS 2653-16-9) can match the original's performance without process revalidation. This compound, also known as N-methyl-4-nitrochloroacetanilide, serves as a critical Nintedanib intermediate in organic synthesis. Our product is manufactured under strict quality assurance protocols to ensure it functions identically in downstream coupling steps. The typical industrial purity exceeds 98%, with a single maximum impurity threshold of ≤0.5%. However, please refer to the batch-specific COA for exact values, as minor variations may occur due to synthesis route optimizations. We offer two standard grades: Technical Grade (≥98%) and Purified Grade (≥99%), both suitable for pharmaceutical intermediate applications. The table below summarizes the key technical parameters.
| Parameter | Technical Grade | Purified Grade |
|---|---|---|
| Assay (HPLC) | ≥98.0% | ≥99.0% |
| Water Content (KF) | ≤0.5% | ≤0.3% |
| Melting Point | 108-112°C | 109-111°C |
| Appearance | Pale yellow to yellow crystalline powder | Pale yellow crystalline powder |
As a global manufacturer, we understand that consistency is paramount. Our manufacturing process is designed to minimize batch-to-batch variability, ensuring that your synthesis route remains robust. For those transitioning from the original source, we recommend a small-scale trial to confirm identical behavior, though our technical support team can provide comparative data upon request.
Batch-to-Batch Spectral Fingerprint Consistency: HPLC Retention Time Drift and Trace Halogenated Solvent Residuals
One of the most overlooked aspects when qualifying a drop-in replacement is the spectral fingerprint consistency. In our experience, even minor shifts in HPLC retention time can indicate subtle differences in impurity profiles that may affect coupling efficiency. For 2-Chloro-N-methyl-N-(4-nitrophenyl)acetamide, we monitor retention time drift across batches with a tolerance of ±0.1 minutes under standardized conditions. This tight control is achieved through rigorous in-process checks and final product testing. Additionally, trace halogenated solvent residuals—a common byproduct of the synthesis route—are kept below 100 ppm for dichloromethane and 50 ppm for chloroform, as confirmed by headspace GC. These levels are well within industry norms and do not interfere with subsequent reactions. A field note: in some cases, we have observed that residual solvents can slightly alter the crystal habit, which may affect dissolution rates in certain solvent systems. If your process is sensitive to this, we can provide material with adjusted residual profiles upon request.

COA Data Structures, Certificate Traceability, and Assay Variance Limits vs. Original Benchmark
Every shipment of our 2-Chloro-N-methyl-N-(4-nitrophenyl)acetamide includes a comprehensive Certificate of Analysis (COA) that mirrors the data structure of the original US-CATO C4X-18147 documentation. This includes HPLC chromatograms, residual solvent analysis, water content, and melting point. We assign a unique batch number that allows full traceability back to raw material lots and production records. Our assay variance limits are set at ±0.5% for Technical Grade and ±0.3% for Purified Grade, ensuring that your process validation remains intact. To verify authenticity, customers can cross-reference the COA with our secure online portal or contact our quality assurance team directly. This level of transparency is critical for QC directors who need to maintain regulatory compliance without additional auditing burdens. For German-speaking partners, we also provide documentation in German; refer to our article on Lösung von Hydrolyse-Nebenreaktionen in den Kupplungsschritten von CAS 2653-16-9 for technical details.
Bulk Packaging and Logistics: IBC, 210L Drums, and Handling of Non-Standard Parameters
Bulk sourcing requires careful consideration of packaging and logistics to maintain product integrity. We supply 2-Chloro-N-methyl-N-(4-nitrophenyl)acetamide in standard 210L drums (net weight 25 kg or 50 kg) and IBC totes (500 kg or 1000 kg) for larger orders. All packaging is UN-approved and suitable for international transport. A non-standard parameter that often arises in the field is the compound's behavior at low temperatures. While the melting point is around 110°C, we have observed that at sub-zero storage temperatures (e.g., -20°C), the crystalline powder can develop slight electrostatic charges, leading to clumping. This does not affect chemical purity but may require gentle agitation before use. Our logistics team can advise on proper storage conditions to mitigate this. Custom packaging options, such as vacuum-sealed aluminum foil bags inside drums, are available to enhance stability during long transit times. We focus on physical packaging robustness to ensure your material arrives in specification, without making claims about environmental certifications.

For procurement managers, this means predictable pricing and consistent availability, which are critical for long-term project planning.
Frequently Asked Questions
What is the typical lot-to-lot assay variance for your 2-Chloro-N-methyl-N-(4-nitrophenyl)acetamide?
Our Technical Grade typically shows an assay variance of ±0.5%, while Purified Grade is within ±0.3%. These limits are verified by HPLC and documented on each COA. We recommend reviewing batch-specific data for your qualification.
How can I verify the authenticity of the Certificate of Analysis?
Each COA includes a unique batch number and QR code that links to our secure database. You can also contact our quality assurance team directly to confirm the document's validity and request additional supporting data.
What are the minimum order quantities for bulk supply?
For initial trials, we offer smaller quantities (e.g., 1 kg) to allow process evaluation. For bulk orders, the minimum is typically 25 kg (one 210L drum). We can discuss flexible terms for long-term contracts.
Does your product require special storage conditions?
Store in a cool, dry place away from direct sunlight. While the compound is stable at ambient temperatures, we have noted that at sub-zero temperatures, electrostatic clumping may occur. This does not affect purity but can be mitigated by gentle agitation before use.
Can you provide custom packaging for air-sensitive processes?
Yes, we offer custom packaging options such as vacuum-sealed aluminum foil bags inside drums or IBC totes to protect the product during transport and storage. Please discuss your requirements with our sales team.
