- Critical Identity: CAS 13161-30-3, Molecular Formula C5H5NO2, Molecular Weight 111.1 g/mol.
- Quality Standard: Industrial grade specifications typically target ≥99.0% purity via advanced crystallization.
- Documentation: Comprehensive COA, SDS, and COO available for regulatory compliance and customs clearance.
In the realm of fine chemical procurement, particularly for pharmaceutical intermediates and agrochemical synthesis, the Certificate of Analysis (COA) serves as the definitive document for quality assurance. For buyers sourcing 2-Hydroxypyridine N-oxide, understanding the technical nuances within the COA is paramount to ensuring reaction consistency and final product efficacy. This compound, often abbreviated as HOPO, is a critical building block in organic synthesis, requiring rigorous validation of its physical and chemical properties before integration into large-scale manufacturing process workflows.
Industrial buyers must look beyond basic identity confirmation. A robust COA provides data on melting point ranges, assay purity, impurity profiles, and residual solvent limits. When evaluating suppliers for 2-Pyridinol-1-oxide, procurement managers should prioritize vendors who offer transparent batch-specific data rather than generic specification sheets. This level of transparency is essential for maintaining Good Manufacturing Practice (GMP) standards in downstream applications.
Key Quality Metrics in Industrial-Grade Specifications
The transition from research-grade to industrial-grade chemicals involves stringent controls over impurity profiles. While standard laboratory reagents may suffice for small-scale assays, bulk production requires industrial purity levels that minimize side reactions and maximize yield. The following table outlines the critical technical parameters expected in a high-quality COA for this substance.
| Parameter | Specification Standard | Typical Industrial Result |
|---|---|---|
| CAS Number | 13161-30-3 | 13161-30-3 |
| Molecular Formula | C5H5NO2 | C5H5NO2 |
| Molecular Weight | 111.1 g/mol | 111.1 g/mol |
| Appearance | Off-white to Light Yellow Powder | Off-white Crystalline Powder |
| Melting Point | 147.0°C to 152.0°C | 148.5°C to 151.0°C |
| Purity (HPLC/GC) | ≥ 97.0% (Research Grade) | ≥ 99.0% (Industrial Grade) |
| Loss on Drying | ≤ 0.5% | ≤ 0.3% |
Attention to the melting point range is particularly vital. A narrow melting point range, such as 148.5°C to 151.0°C, indicates a high degree of crystalline uniformity and low impurity content. Broad ranges often suggest the presence of isomers or incomplete reaction byproducts from the synthesis route. Furthermore, industrial buyers should verify that the COA includes data on heavy metals and residual solvents, as these are critical for pharmaceutical regulatory filings.
Ensuring ≥99.0% Purity Compliance for Pharmaceutical Intermediates
The demand for high-purity intermediates is driven by the need to reduce purification steps in downstream synthesis. In pharmaceutical development, this compound serves as a key intermediate in synthesizing various pharmaceuticals, particularly those targeting neurological disorders. Impurities at this stage can propagate through the synthesis tree, complicating final drug substance purification and potentially affecting safety profiles.
Advanced manufacturing facilities utilize optimized oxidation and purification techniques to achieve purity levels exceeding 99.0%. This often involves multiple recrystallization steps or column chromatography during the production phase. A reliable global manufacturer will document these quality control measures in the Product Specification (PS) document accompanying the COA. Buyers should request historical data on batch consistency to ensure that the supplier can maintain these standards over long-term contracts.
For those managing supply chains, securing a stable bulk price is often correlated with purity guarantees. Higher purity grades may command a premium, but the cost savings realized through improved reaction yields and reduced waste disposal often outweigh the initial material cost. NINGBO INNO PHARMCHEM CO.,LTD. specializes in providing these high-specification intermediates, ensuring that every shipment is backed by rigorous internal quality control protocols and third-party verification where required.
Applications and Technical Utilization
Beyond pharmaceutical synthesis, the versatility of 2-Hydroxypyridine N-oxide extends into several high-value industrial sectors. Understanding these applications helps procurement teams justify inventory levels and forecast demand accurately.
- Pharmaceutical Development: Enhances drug efficacy and specificity in complex organic syntheses, particularly for heterocyclic compounds.
- Analytical Chemistry: Employed as a reagent for the detection and quantification of metal ions in environmental samples, providing a reliable method for monitoring pollution levels.
- Agricultural Chemistry: Used in formulating agrochemicals, including fungicides and herbicides, improving crop protection and yield through effective action against pests.
- Material Science: Plays a role in developing advanced materials, such as polymers and coatings, that require enhanced thermal stability and resistance to degradation.
- Biochemistry: Utilized in biochemical assays to study enzyme activity and metabolic pathways, aiding in the understanding of complex biological processes.
Each application imposes different purity requirements. For instance, material science applications may tolerate slightly broader impurity profiles compared to active pharmaceutical ingredient (API) synthesis. However, maintaining a standard of industrial purity across all batches ensures flexibility in usage and prevents cross-contamination in multi-purpose facilities.
Safety, Storage, and Regulatory Documentation
Proper handling and storage are critical to maintaining the integrity of the chemical post-delivery. The Safety Data Sheets (SDS) provide comprehensive safety information on handling, storage, and disposal of the product. Typically, this compound should be stored in a cool, dry place, with recommended temperatures around -20°C for long-term stability, although room temperature shipping is often feasible for short durations.
Regulatory compliance is facilitated through comprehensive documentation packages. In addition to the COA, buyers should secure Certificates of Origin (COO). This COO confirms the country where the product was manufactured and details whether it is derived from natural, synthetic, or other specific sources. This certificate may be required for customs, trade, and regulatory compliance, especially when importing into regions with strict chemical control laws.
When sourcing these materials, partnering with an established entity like NINGBO INNO PHARMCHEM CO.,LTD. ensures access to a complete documentation suite. This includes batch-specific COAs searchable by lot number, ensuring traceability from the reactor to the end user. Such traceability is indispensable for audit readiness and quality management systems.
Conclusion: Strategic Procurement for High-Value Intermediates
The procurement of 2-Hydroxypyridine N-oxide requires a balance of technical scrutiny and commercial acumen. By prioritizing suppliers who provide detailed COAs, maintain high industrial purity standards, and offer robust regulatory documentation, businesses can safeguard their production pipelines. Whether for neurological drug development or advanced material coating, the quality of the starting material dictates the success of the final product. Engaging with a dedicated global manufacturer ensures consistency, compliance, and competitive bulk price structures for long-term industrial partnerships.
