Drop-In Replacement For Sigma-Aldrich SY3H3D67F3DC HMBCG

Technical Specification Matrix: Assay ≥98.5%, Moisture ≤0.5%, and Heavy Metal Limits for HMBCG

N,N'''-1,6-Hexanediylbis(N'-cyanoguanidine) (CAS: 15894-70-9) serves as a critical biocidal intermediate in water treatment, coating preservation, and agricultural formulations. At NINGBO INNO PHARMCHEM CO.,LTD., we engineer this compound to meet rigorous industrial purity standards, ensuring seamless integration into existing production lines. The baseline technical matrix below outlines the core parameters validated during our manufacturing process. Procurement and R&D teams should note that while assay and moisture limits are fixed, trace impurity profiles and heavy metal thresholds are batch-verified.

Parameter Specification Test Method
Assay (Purity) ≥98.5% HPLC
Moisture Content ≤0.5% Karl Fischer Titration
Heavy Metals (as Pb) Please refer to the batch-specific COA ICP-OES
Residual Solvents Please refer to the batch-specific COA GC-FID
Particle Size (D90) Please refer to the batch-specific COA Laser Diffraction

These parameters are calibrated to support high-throughput synthesis routes without requiring formulation recalibration. Our quality assurance protocols ensure that every shipment aligns with the documented matrix, minimizing downtime during raw material transitions.

Certificate of Analysis (COA) Parameters: HPLC Purity Grades, Residual Solvent Thresholds, and Batch Traceability

Procurement managers evaluating a chemical supplier must prioritize transparent documentation. Our COA provides a complete breakdown of HPLC purity grades, explicitly separating the main peak from known byproducts such as unreacted guanidine derivatives or dimeric species. Residual solvent thresholds are quantified using GC-FID, with limits strictly aligned with ICH Q3C guidelines for industrial intermediates. Each batch carries a unique traceability code that links back to raw material intake, reaction temperature logs, and final filtration cycles. This level of documentation eliminates guesswork during vendor qualification audits and supports rapid technical support escalation when formulation anomalies occur.

Bulk Packaging & Logistics Specifications: 25kg HDPE Drums, 200kg IBC Totes, and Thermal Stability Data

Physical handling protocols directly impact material integrity during transit. We ship HMBCG in 25kg HDPE drums for standard laboratory and pilot-scale operations, and 200kg IBC totes for continuous industrial manufacturing. All containers are sealed with nitrogen-flushed headspace to prevent atmospheric moisture ingress. Factual shipping methods include standard dry freight via FCL or LCL, with palletized stacking limited to two tiers to prevent drum deformation. During winter transit across northern logistics corridors, HMBCG exhibits a tendency to form fine surface crystallization when ambient temperatures drop below 5°C. This is a physical phase shift, not chemical degradation. Field data confirms that storing the material at 15–25°C for 48 hours prior to formulation restores optimal flowability without impacting the synthesis route or final biocidal performance. Thermal stability testing indicates no exothermic decomposition below 180°C under inert conditions.

Direct Sigma-Aldrich SY3H3D67F3DC Cross-Reference: Melting Point, Particle Size Distribution, and Functional Equivalence

When evaluating a drop-in replacement for Sigma-Aldrich SY3H3D67F3DC, procurement teams require identical technical parameters without supply chain volatility. Our 1,6-Hexamethylene-bis-cyanoguanidine matches the reference material in melting point behavior, particle size distribution, and functional equivalence across aqueous and solvent-based systems. We maintain consistent D50 and D90 ranges to ensure predictable dissolution kinetics and prevent nozzle clogging in spray-drying or high-shear mixing applications. By standardizing on our manufacturing process, buyers achieve measurable cost-efficiency while retaining formulation performance. Supply chain reliability is reinforced through dual-reactor capacity and scheduled production cycles, eliminating the lead-time fluctuations common with specialty chemical distributors. Technical equivalence is verified through side-by-side HPLC overlay testing and dissolution rate comparisons.

Industrial Formulation Metrics: Viscosity Impact, pH Stability, and Biocidal Efficacy at 0.1–0.5% Loadings

Integration into commercial formulations requires precise control over rheological and chemical stability. At 0.1–0.5% loadings, HMBCG demonstrates minimal viscosity impact in waterborne dispersions, maintaining pumpability without thickener adjustment. pH stability remains consistent between 4.0 and 9.0, with hydrolysis rates remaining negligible under standard storage conditions. Biocidal efficacy against common microbial strains is preserved across this concentration window, provided dispersion homogeneity is maintained. Trace amine impurities above 0.05% can induce a slight yellowing in clear resin matrices during high-shear mixing. Our purification protocol keeps amine residuals below detectable limits, ensuring color neutrality in transparent coatings and adhesives. For exact dissolution rates and compatibility indices, please refer to the batch-specific COA.

Frequently Asked Questions

What is the minimum order quantity for bulk HMBCG shipments?

Our standard MOQ for 25kg HDPE drums is 500kg, while 200kg IBC totes require a minimum of 1000kg per shipment. Custom lot sizes can be arranged for pilot testing or phased production ramps.
