Phenyl Dichlorophosphate Supplier: High Purity, In Stock?
Practical Insights on Phenyl Dichlorophosphate for Real-World Production
If you spend time around resin modifiers, flame-retardant intermediates, or specialty agrochemical building blocks, you’ve probably bumped into Phenyl Dichlorophosphate sooner or later. It’s one of those quiet workhorse reagents that rarely headline a press release, yet it keeps showing up in project specs. I’ve seen procurement teams favor it for clean phosphorylation routes and steady QC. And yes, the market’s shifting—toward higher purity, lower hydrolyzable chloride, and audited supply chains that don’t implode under rush orders.
Technical Snapshot
| Name | Phenyl Dichlorophosphate |
| CAS | 770-12-7 |
| Formula / MW | C6H5Cl2O2P / 210.98 g·mol⁻¹ |
| Appearance | Colorless to pale-yellow liquid (real-world lots may vary slightly) |
| Typical Purity | ≥99.0% by GC (area %) |
| Moisture | ≤0.05% (KF, ASTM E203) |
| Color (APHA) | ≤40 (freshly packed) |
Applications and Advantages
- Intermediate for aryl phosphate esters (flame-retardant additives, plasticizers).
- Phosphorylation reagent in specialty monomers and resin modifiers for electronics-grade epoxies.
- Synthesis of agrochemical and lubricant additive intermediates where controlled reactivity matters.
Why do formulators pick Phenyl Dichlorophosphate? Controlled reactivity, generally low color drift, and consistent GC profiles. Many customers say it’s easier to scale than some mixed-aryl alternatives, especially when they can lock in water specs.
Process Flow (high level)
Materials: chlorophosphoryl source, phenolic feedstock, solvent system (anhydrous), and acid scavenger. Methods: controlled addition under dry, inert atmosphere; moderated exotherm; phased aging; then vacuum finishing. QA checks: GC assay and related substances, KF moisture (ASTM E203), acidity/Cl⁻ by titration, color (APHA), specific gravity. Packaging under nitrogen with tamper-evident seals. Service life is typically around 12–24 months in unopened drums, stored cool and dry, though actual shelf life depends on headspace and handling.
Vendor Landscape (what buyers compare)
| Vendor | Purity (GC) | Moisture | Lead Time | Certs |
|---|---|---|---|---|
| Sincere Chemicals (Origin: Jinling Mansions No.106-1 East Yuhua Rd., Shijiazhuang, Hebei, China) | ≥99.0% (typical 99.2% ≈) | ≤0.05% | 2–4 weeks, ex-works (seasonal) | ISO 9001; REACH-ready docs |
| Regional Trader A | ≈98.5–99.0% | ≤0.10% | Stock-dependent | CoA; SDS |
| Boutique Lab Supplier | ≥99.0% (small lots) | ≤0.05% | Made-to-order | ISO 17025 test reports |
Customization and Packaging
- Grades: standard (≥99.0% GC), low-moisture spec, or tighter color control for optics-adjacent uses.
- Packaging: 200 kg steel drums, 1,000 L IBCs, or 25 kg lab packs with nitrogen blanket.
- Docs: SDS (GHS/CLP), CoA per lot, method sheets; third-party testing on request (ISO/IEC 17025).
Case Notes (field feedback)
• An epoxy modifier plant in Southeast Asia reported ≈1.5–2.0% yield stabilization after moving to tighter KF control on Phenyl Dichlorophosphate.
• A specialty additives customer noted lower APHA drift over 60 days when switching to nitrogen-packed drums—small change, material impact on QC holds.
Quality, Standards, and Test Data
Recent batch example (illustrative): GC assay 99.2%; moisture 0.03% (ASTM E203); color 30 APHA; density 1.35 g/mL @ 25°C. Compliance support: ISO 9001 QMS, GHS/CLP labeling, REACH data-ready, and transport per UN/IMDG/IATA as applicable. Always verify local regulations, to be honest; labeling nuances vary.
Industry Trends
Demand is nudging upward from electronics resins and safer flame-retardant chemistries. In fact, buyers increasingly ask for sub-0.05% moisture and documented low residuals. Surprisingly, lead-time agility beats penny-per-kilo pricing in many RFQs right now.
