Photoinitiator 1173 Bulk Price Specs & Technical Data
Detailed Photoinitiator 1173 Technical Specs: C10H12O2, Assay, and Physical Properties
Photoinitiator 1173, chemically identified as 2-Hydroxy-2-Methylpropiophenone (HMPP), operates as a Type I radical photoinitiator essential for UV-curable formulations. The molecular formula C10H12O2 dictates its solubility profile and reactivity under UV exposure. Procurement specifications must prioritize assay purity, typically exceeding 97%, to ensure consistent cure speeds and minimize residual odor in final coatings. The compound exhibits a molecular weight of 164.20 g/mol, with a density of 1.077 g/cm³ at 25°C, which influences dosing calculations in automated mixing systems.
For formulators evaluating Photoinitiator 1173 HMPP technical data, the refractive index of 1.533 indicates compatibility with high-solid acrylic resins. The boiling point ranges between 102°C and 103°C at 4 mmHg, suggesting low volatility during storage but requiring controlled temperatures during high-speed curing processes to prevent evaporation losses. The flash point exceeds 110°C, classifying it as a combustible liquid requiring standard chemical storage protocols. Appearance is typically a yellowish liquid, though variations in hue may occur based on purification levels without affecting photolytic efficiency.
The following table outlines critical physical and chemical parameters required for quality control validation against industry standards:
| Parameter | Specification Standard | Typical Analysis Result | Test Method |
|---|---|---|---|
| CAS Number | 7473-98-5 | 7473-98-5 | Verification |
| Molecular Formula | C10H12O2 | C10H12O2 | MS |
| Assay (Purity) | ≥ 97.0% | 97.5% - 98.5% | GC-MS |
| Appearance | Yellowish Liquid | Clear Yellowish Liquid | Visual |
| Density (25°C) | 1.070 - 1.080 g/cm³ | 1.077 g/cm³ | ASTM D4052 |
| Refractive Index (25°C) | 1.530 - 1.540 | 1.533 | ASTM D1218 |
| Water Content | ≤ 0.5% | 0.2% | Karl Fischer |
| Flash Point | > 110°C | 112°C | Pensky-Martens |
GC-MS analysis is critical for detecting impurities such as unreacted ketones or oxidation byproducts that can inhibit polymerization. High-purity grades ensure minimal yellowing in clear coat applications, making this UV Initiator 1173 suitable for wood finishes and plastic coatings where aesthetic clarity is paramount.
Photoinitiator 1173 Bulk Price Structure: Volume Tiers and Cost Efficiency
Bulk pricing for Photoinitiator 1173 is structured around volume tiers that reflect synthesis scale and logistics efficiency. Entry-level procurement typically starts at MOQs of 25kg, suitable for pilot batches or R&D validation. Industrial-scale contracts involving metric ton quantities secure significant cost reductions per kilogram due to optimized reactor utilization and reduced packaging overhead. Price fluctuations correlate with raw material availability, specifically propiophenone derivatives, and energy costs associated with fractional distillation.
Cost efficiency is not solely determined by unit price but by performance dosage. Because HMPP exhibits high molar extinction coefficients, lower loading rates are often required compared to less efficient initiators, offsetting higher raw material costs. Procurement managers should evaluate total formulation cost rather than isolated ingredient pricing. Long-term supply agreements stabilize pricing against market volatility, ensuring consistent budgeting for coating production lines. Discounts are frequently applied for full container load (FCL) shipments, reducing freight costs per unit weight.
Industrial Packaging Standards: HDPE Drum Dimensions and Storage Requirements
Standard industrial packaging for Photoinitiator 1173 utilizes HDPE drums to ensure chemical compatibility and structural integrity during transit. Common configurations include 25kg net weight drums, with dimensions optimized for palletization and warehouse stacking. Each drum is sealed with induction liners to prevent moisture ingress and solvent evaporation, preserving the assay integrity upon arrival. Bulk liquid shipments may utilize IBC totes for high-volume consumers, reducing plastic waste and handling time.
Storage requirements mandate keeping containers in a cool, dry, and well-ventilated area away from direct sunlight. UV exposure prior to formulation can prematurely activate the photoinitiator, leading to gelation or viscosity changes in the bulk stock. Temperatures should be maintained between 5°C and 30°C to prevent crystallization or thermal degradation. Darocur 1173 equivalents share these storage protocols, requiring strict inventory rotation (FIFO) to ensure the oldest stock is utilized first. Drum labels must include hazard warnings and batch numbers for traceability during quality audits.
Quality Assurance Protocols: ISO Certifications and Regulatory Compliance for Procurement
Quality assurance protocols at NINGBO INNO PHARMCHEM CO.,LTD. adhere to strict ISO management systems, ensuring batch-to-batch consistency. Every shipment is accompanied by a Certificate of Analysis (COA) detailing GC-MS purity profiles, density measurements, and refractive index values. Procurement teams should verify that COA data matches internal specification limits before releasing materials to production. Regular internal audits monitor synthesis parameters to prevent deviations in impurity profiles that could affect cure depth.
For facilities requiring validated alternatives, understanding the Photoinitiator 1173 Irgacure 1173 Drop-In Replacement Equivalent Supplier criteria is essential for seamless transitions. Regulatory compliance focuses on global chemical inventory listings and safety data sheet accuracy rather than specific regional registrations. Documentation must support safe handling procedures and environmental disposal guidelines. Quality control laboratories perform HPLC and GC testing on random samples from each production run to confirm adherence to the 97% assay minimum. This rigorous testing regime minimizes the risk of formulation failures due to substandard raw materials.
Supply Chain Reliability: Lead Times and Inventory Stability for UV Systems
Supply chain reliability is critical for maintaining continuous operation in UV curing systems. Lead times for Photoinitiator 1173 typically range from 2 to 4 weeks for standard orders, depending on port logistics and customs clearance. Inventory stability is maintained through strategic stockpiling of key intermediates, allowing for rapid scale-up during demand surges. Manufacturers prioritize production scheduling to accommodate urgent procurement needs without compromising quality testing phases.
