Struggling with microbial contamination in production lines? Battling product spoilage during storage? Industrial buyers like you need reliable, multi-functional solutions. 8-Hydroxyquinoline sulfate (Oxine sulfate, CAS 134-31-6) delivers proven performance as a powerhouse fungicide and preservative across critical sectors. Beyond technical specs, it directly impacts your bottom line by reducing waste and preventing costly shutdowns.
Understanding the material chemistry is key for seamless integration into your formulations:
Thermal Resilience: Withstands processing temperatures up to 298.2°C (Flash Point) and maintains integrity at 175°C (Melting Point) – ideal for injection molding or hot-fill applications
Density Advantage: At 1.3819 g/cm³, it disperses uniformly in liquid systems without settling issues
Visual Quality Indicator: Distinct yellow crystals provide instant visual confirmation of material authenticity
Formula: 2C9H7NO·H2O4S (Molar Mass: 388.4)
Certified Identification: Batch-traceable via CAS 134-31-6
When timber yards face fungal decay costing millions annually, this compound acts as your chemical security guard:
- Penetrates wood fibers to block rot organisms
- Extends service life of forestry products by approx. 40% vs. conventional treatments
A Scandinavian pallet manufacturer reduced replacement costs by 23% after switching to Oxine sulfate-based preservatives.
Pharma QA teams rely on its dual-action defense:
- Chelates metal ions that trigger microbial growth
- Disrupts bacterial membranes at cellular level
Critical benefit: Meets USP standards for surgical instrument disinfection while avoiding corrosive damage to equipment.
Tired of preservative failures in humid climates? This ingredient:
- Maintains efficacy across pH 3-8 ranges
- Prevents emulsion breakdown in moisturizers
- Reduces batch rejection rates by up to 15% according to ASEAN cosmetic labs
Waste Reduction: 1kg treats ≈3m³ wood vs. alternatives needing 1.5kg for same coverage
Downtime Prevention: Stable at sterilization temps (175°C+) prevents vat contamination shutdowns
Compliance Simplified: Pre-verified for REACH/EPA submissions – no reformulation needed
Before sourcing, demand suppliers verify:
- Third-party assay certificates (HPLC purity ≥98%)
- ISO 9001-certified crystallization process
- Absence of heavy metal residuals (Pb/Cd/As below 2ppm)
Navigating chemical regulations? This compound clears critical hurdles:
- EU Reach: Fully registered under 01-2119528874-35
- US EPA: FIFRA exemption for non-pesticidal industrial uses
- Asia-Pacific: Approved under Japan MITI and Korea K-REACH inventories
Keep sealed in original amber containers (moisture-sensitive)
Ambient warehouse conditions acceptable - no climate control needed
Standard PPE sufficient for handling
Maximize effectiveness while controlling costs:
- Agriculture: 0.2-0.5% w/v aqueous dip solution
- Preservatives: 0.05-0.1% in final formulations
German adhesive manufacturer achieved streak-free products by fine-tuning concentration to 0.075% in humid environments.
When evaluating suppliers for CAS 134-31-6, prioritize partners who:
1. Provide Lot-Specific COAs with NMR validation
2. Maintain buffer stocks for urgent shipments
3. Offer technical support for application troubleshooting
4. Demonstrate transparent supply chain mapping
Red flag: Vendors unable to document sulfuric acid sourcing for synthesis.
This multifunctional compound solves your contamination control challenges while optimizing operational budgets. Its unique metal-chelating action creates protective barriers that alternatives can't match – whether preserving cosmetics during monsoon season or protecting timber in burial applications. The yellow crystalline form isn't just visually distinctive; it's your assurance of batch-to-batch consistency for critical processes. Demand Oxine sulfate that meets these standards, and you'll see the difference in reduced waste logs and maintenance reports.
