Bulk Price 2-(2,5-Diaminophenyl)Ethanol Sulfate 2026: Industrial Procurement Guide
- Market Dynamics: Research-grade pricing exceeds $8,000/kg, while industrial bulk contracts offer significant volume discounts.
- Technical Specs: CAS 93841-25-9 requires strict storage under inert gas due to hygroscopic stability profiles.
- Supply Chain: Secure sourcing from a verified global manufacturer ensures consistent oxidative dye intermediate quality.
The cosmetic chemistry sector relies heavily on precise molecular intermediates to ensure safety and efficacy in final formulations. As we approach 2026, the demand for specialized hair dye precursor compounds continues to rise, driven by the global expansion of personal care markets. Among these, 2-(2,5-Diaminophenyl)ethanol sulfate (CAS: 93841-25-9) stands out as a critical component for oxidative coloring systems. Procurement professionals must navigate a complex landscape where research-grade pricing models differ drastically from industrial-scale contracts. Understanding the technical nuances of synthesis, purity standards, and logistics is essential for securing favorable bulk price agreements.
Analyzing Bulk Price Trends Versus Research Grade Costs
Market intelligence data indicates a significant disparity between small-pack laboratory pricing and industrial procurement costs. Analysis of available market listings shows that small quantities (50mg to 10g) often carry a premium equivalent to over $8,000 per kilogram. For instance, 1kg packages listed in research catalogs can reach prices upwards of $8,125, reflecting the high overhead of handling hygroscopic solids in small batches. In contrast, industrial buyers negotiating directly with a global manufacturer can access vastly improved economics through volume-based tiering.
The price variance is primarily driven by packaging, purification levels, and regulatory documentation. Research suppliers often provide material with standard analytical certificates suitable for R&D but insufficient for commercial cosmetic production. Industrial contracts typically require comprehensive Certificates of Analysis (COA), stability data, and adherence to ISO or GMP standards. When evaluating suppliers for 2-(2,5-Diaminophenyl)ethanol sulfate, procurement managers should prioritize vendors who demonstrate capacity for multi-ton synthesis rather than simple repackaging of laboratory stocks.
Comparative Pricing Structure (Estimated)
| Pack Size | Estimated Unit Price (USD) | Price Per Kg Equivalent | Target Sector |
|---|---|---|---|
| 5g - 10g | $120 - $360 | $24,000 - $36,000 | Laboratory R&D |
| 100g - 500g | $500 - $2,000 | $5,000 - $10,000 | Pilot Scale |
| 1kg - 5kg | $4,000 - $8,500 | $4,000 - $8,500 | Small Batch Production |
| 25kg - Drum | Contract Basis | Significantly Reduced | Industrial Manufacturing |
Technical Specifications and Synthesis Routes
From a process chemistry perspective, 2-(2,5-Diaminophenyl)ethanol sulfate is valued for its stability and solubility profile compared to its free base counterpart. The molecule, with a molecular weight of 250.27 g/mol, presents as a light purple solid. A critical technical consideration is its hygroscopic nature, which necessitates storage under inert gas (nitrogen or Argon) at 2-8°C to prevent degradation. This sensitivity underscores the importance of robust packaging solutions during transit to maintain industrial purity standards upon arrival.
The synthesis typically involves the sulfation of 2-(2,5-diaminophenyl)ethanol. Achieving high yields requires precise control over reaction temperatures and acid concentrations to avoid over-sulfation or oxidation of the amine groups. The resulting stable salt form offers improved handling characteristics for formulators, reducing the risk of airborne particulates compared to free base powders. As an oxidative dye intermediate, it must meet strict limits on heavy metals and residual solvents to comply with international cosmetic regulations such as EU Regulation 1223/2009.

Logistics and Supply Chain Stability for Global Manufacturer Orders
Securing a reliable supply chain for cosmetic raw materials is paramount for maintaining production schedules. Lead times can vary significantly depending on the supplier's inventory model. Research catalogs often list lead times of 6 to 8 days for gram quantities, but industrial drums may require production scheduling. Partnering with a dedicated entity like NINGBO INNO PHARMCHEM CO.,LTD. ensures that bulk orders are prioritized with consistent quality control protocols. This reduces the risk of batch-to-batch variability, which is crucial for maintaining color consistency in final hair dye products.
Logistics for this compound require careful attention due to its classification and stability requirements. While vapor pressure is negligible (0Pa at 20℃), the hygroscopic nature means moisture barriers are essential during shipping. Global manufacturers typically utilize double-lined drums with desiccants to ensure the material arrives within specification. Furthermore, regulatory documentation, including REACH compliance and safety data sheets (SDS), must be readily available to facilitate customs clearance in key markets such as the EU and North America.
Procurement Best Practices
- Request Pre-Shipment Samples: Always validate purity and color profile before committing to full drum quantities.
- Verify Storage Capabilities: Ensure your facility can maintain the required 2-8°C environment upon receipt.
- Negotiate Blanket Orders: Lock in pricing for yearly requirements to mitigate market volatility.
- Audit Quality Systems: Confirm the supplier operates under relevant quality management systems for cosmetic intermediates.
In conclusion, the 2026 market for 2-(2,5-Diaminophenyl)ethanol sulfate favors buyers who distinguish between research-grade premiums and industrial manufacturing capabilities. By focusing on technical specifications, storage integrity, and verified supply chains, procurement teams can optimize costs without compromising quality. NINGBO INNO PHARMCHEM CO.,LTD. remains committed to providing high-purity intermediates that meet the rigorous demands of the modern cosmetic industry, ensuring stable supply and competitive pricing for long-term partners.
