Product Overview & Core Applications

Lithium Phenyl(2,4,6-trimethylbenzoyl)phosphinate (commonly known as LAP, CAS: 85073-19-4) is a world-class premium, water-soluble photoinitiator at the forefront of regenerative medicine and biomaterials science. Categorized as an advanced Photoinitiator Material, it is widely used for the crosslinking and cross-polymerization of hydrogels or other structural polymer matrices.

Lithium Phenyl(2,4,6-trimethylbenzoyl)phosphinate

Compared to traditional, commonly used photoinitiators (such as Irgacure 2959), LAP possesses distinct physicochemical properties that offer irreplaceable advantages in biological applications and tissue engineering:

  • Excellent Water Solubility & Cytocompatibility: LAP exhibits exceptional solubility in aqueous environments and features outstanding cell compatibility with no inherent toxicity to living cells. This makes it the premier choice for bioactive hydrogel formulation, 3D bioprinting, cell encapsulation, and 3D cell culture scaffolds.

  • Enhanced Sensitivity & Fast Polymerization Rate: Under standard 365 nm UV light, LAP demonstrates extremely high photoinitiation efficiency, allowing for a much faster polymerization rate. This significantly decreases the UV exposure time and subsequent radiation damage to living cells.

  • Visible-Light Driven Polymerization (400 nm): LAP exhibits notable absorbance at 400 nm (blue/visible light range). This allows polymerization to be triggered using gentle, visible blue light instead of harsh UV rays, further safeguarding the viability of sensitive biological samples, stem cells, and delicate primary cultures.

Because LAP requires an intricate synthesis route and high-precision purification, catalog suppliers routinely experience supply gaps or charge excessive premiums, hindering industrial pilot testing. Utilizing our mature production structures and advanced refinement systems, we have broken through these bottlenecks. We proudly offer 95% high-purity LAP with a reliable, continuous monthly capacity of 5kg to support your pilot scale-up and new industrial formulations.
Core Advantages

  • 95% High Purity (Bio-Grade Monitored): Refined via specialized, localized purification. Free inorganic salts, structural synthesis byproducts, and residual solvents are strictly restricted. This yields a highly clean substrate with an exceptional cell safety window, minimizing any risk of impurity-induced data distortion in cellular or tissue engineering assays.

  • Stable Industrial Monthly Capacity (5kg/Month): We eliminate the market bottleneck of "unstable supply chains and minor catalog reagent constraints." Our standardized facilities guarantee a stable output of 5kg per month, supporting everything from bulk sampling to continuous commercial procurement.

  • Broad Light-Source Compatibility: Beyond standard UV curing setups (365 nm), LAP perfectly matches modern, high-precision 3D bioprinters equipped with主流 405 nm DLP/SLA lasers or visible-light LED light engines, providing sharp printing resolution and minimal shrinkage.

  • Rigorous Quality Control (QbD): Produced under rigid quality management structures. Every single dispatch is accompanied by a thorough testing booklet comprising a COA (Certificate of Analysis) and HPLC/NMR reports to guarantee batch-to-batch consistency and complete traceability.
