Sourcing 3-Phenoxybenzaldehyde Cyanohydrin: Bulk Supply & COA
Technical Specifications and Purity Grades of 3-Phenoxybenzaldehyde Cyanohydrin
As a critical pyrethroid intermediate, 3-phenoxybenzaldehyde cyanohydrin (CAS 52315-06-7) serves as the backbone for synthesizing high-performance insecticides. This chemical building block is typically supplied at industrial purities of 95% or 98%, with the higher grade often preferred for downstream reactions requiring minimal byproduct formation. The compound, also known as (3-Phenoxyphenyl)glycolonitrile, is a viscous liquid at ambient conditions, with a molecular weight of 239.27 g/mol. Its synthesis route involves the cyanation of 3-phenoxybenzaldehyde, a process that demands rigorous control of residual aldehyde to ensure optimal yield in subsequent esterification steps. For procurement managers, understanding the distinction between technical and pure grades is essential; our standard offering meets or exceeds 98% purity by GC, with detailed specifications available in the batch-specific COA.
| Parameter | Technical Grade | Pure Grade |
|---|---|---|
| Assay (GC) | ≥95% | ≥98% |
| Moisture (KF) | ≤0.5% | ≤0.3% |
| Appearance | Pale yellow liquid | Colorless to pale yellow liquid |
| Residual 3-Phenoxybenzaldehyde | ≤3% | ≤1% |
In field applications, we have observed that the industrial purity grade can exhibit slight viscosity shifts when stored below 5°C, potentially complicating pumping operations. Pre-warming to 15–20°C restores fluidity without degradation, a nuance often overlooked in standard datasheets. For large-scale manufacturing processes, this behavior underscores the importance of proper storage protocols.
Critical COA Parameters and Batch-to-Batch Consistency
When sourcing 3-phenoxybenzaldehyde cyanohydrin, the Certificate of Analysis (COA) is your primary tool for quality assurance. Beyond the basic assay, key parameters include moisture content (by Karl Fischer), color (APHA), and specific gravity. Trace impurities, particularly residual 3-phenoxybenzaldehyde and hydrogen cyanide, must be tightly controlled to avoid side reactions in pyrethroid synthesis. Our industrial synthesis route employs advanced purification steps to minimize these impurities, ensuring batch-to-batch consistency. For instance, our process consistently delivers a product with residual aldehyde below 1%, a critical factor for achieving high enantiomeric excess in chiral synthesis of (S)-2-hydroxy-(3-phenoxy)phenylacetonitrile. Procurement teams should request a representative COA before bulk orders to verify compliance with their specific process requirements. We also provide additional data on request, such as refractive index and density, to support formulation adjustments.
Industrial Handling: Viscosity, Crystallization, and Storage Stability
Handling 3-phenoxybenzaldehyde cyanohydrin at scale requires attention to its rheological properties. At 25°C, the product is a free-flowing liquid, but its viscosity increases noticeably below 10°C. In unheated storage tanks, this can lead to stratification or slow discharge. Our field engineers recommend maintaining storage temperatures between 15–25°C and using nitrogen blanketing to prevent moisture ingress, which can accelerate hydrolysis. Crystallization is rare but can occur if the product is contaminated with water or stored for extended periods at low temperatures. In such cases, gentle warming and agitation restore homogeneity without affecting purity. The compound is stable for at least 12 months under recommended conditions, with no significant degradation observed in accelerated stability studies. For agrochemical precursor applications, these handling characteristics are comparable to those of the parent aldehyde, making it a straightforward drop-in replacement in existing production lines.
Bulk Packaging and Logistics for Large-Scale Procurement
NINGBO INNO PHARMCHEM supplies 3-phenoxybenzaldehyde cyanohydrin in standard industrial packaging: 210L steel drums (net weight 200 kg) and 1000L IBC totes (net weight 1000 kg). Both options are UN-approved for chemical transport and include tamper-evident seals. For intercontinental shipments, drums are palletized and stretch-wrapped, while IBCs are secured in steel frames. We coordinate with major freight forwarders to offer competitive ocean and air freight rates, with typical lead times of 4–6 weeks for bulk orders. Our logistics team can arrange door-to-door delivery, including customs clearance, to major ports worldwide. While we do not handle regulatory compliance for destination countries, we provide full documentation (COA, SDS, packing list) to facilitate importer declarations. For customers transitioning from other suppliers, our packaging dimensions are standardized to fit existing receiving infrastructure, minimizing handling adjustments.
Cost-Efficiency and Supply Chain Reliability as a Drop-in Replacement
As a global manufacturer with dedicated production lines, we offer 3-phenoxybenzaldehyde cyanohydrin at competitive bulk prices without compromising quality. Our integrated supply chain, from raw material sourcing to final purification, ensures a stable supply even during market fluctuations. For buyers currently using alternative sources, our product functions as a seamless drop-in replacement, matching key technical parameters such as assay, moisture, and reactivity. In a recent case, a European agrochemical producer switched to our 98% grade and reported identical yields in their cypermethrin synthesis, with the added benefit of 15% cost savings on a per-kilogram basis. We maintain safety stock of 20 metric tons to buffer against demand spikes, and our production capacity can be scaled to meet annual contracts of 100 MT or more. By choosing NINGBO INNO PHARMCHEM, you gain a partner committed to long-term supply security and technical support.
