For procurement managers, R&D scientists, and formulators in industries leveraging UV curing technology or requiring specialized dye intermediates, sourcing high-quality 4,4'-Bis(diethylamino) Benzophenone (CAS 90-93-7) is a critical task. This compound, known for its efficacy as a Type II photoinitiator and its role in dye synthesis, requires careful procurement to ensure optimal results and cost-effectiveness. As a prominent manufacturer and supplier of this chemical in China, we aim to provide B2B buyers with essential guidance for their purchasing decisions.

Understanding the Product: Key Specifications and Applications

4,4'-Bis(diethylamino) Benzophenone, often referred to by its synonyms like EMK or Ethyl Michler's Ketone, is characterized by its light yellow to yellow-green crystalline powder appearance. The key specifications that buyers should scrutinize include:

• Purity: High purity, typically ≥99.0%, is essential for consistent performance in demanding UV curing applications and precise dye synthesis. Lower purity can lead to unpredictable reaction kinetics and suboptimal final product properties.
• CAS Number: The unique identifier 90-93-7 confirms the exact chemical substance.
• Appearance: Consistent appearance (e.g., crystalline granules, powder) is an indicator of controlled manufacturing processes.
• UV Absorption: Understanding its absorption peaks (e.g., around 248nm and 374nm) helps in matching it with appropriate UV light sources.

Its primary applications include:

• UV Curing: As a Type II photoinitiator, it is vital for the rapid polymerization of monomers and oligomers in coatings, inks, adhesives, and composites.
• Dye Synthesis: It serves as a crucial intermediate in the creation of triarylmethane dyes, prized for their vibrant colors.
• Specialty Uses: Including photosensitization in film and applications in microelectronics.

Navigating the Procurement Process: What Buyers Need to Consider

When procuring 4,4'-Bis(diethylamino) Benzophenone, B2B buyers should focus on several key areas:

1. Supplier Verification: Identify manufacturers with a proven track record in producing high-purity chemicals. Look for companies that provide comprehensive documentation such as Certificates of Analysis (COA), Technical Data Sheets (TDS), and Safety Data Sheets (SDS). As a leading manufacturer in China, we readily provide these documents to ensure transparency and quality assurance.
2. Quality and Consistency: Beyond initial specifications, inquire about the consistency of quality across different batches. Reliable suppliers maintain rigorous quality control protocols.
3. Pricing and Value: While cost is a factor, focus on value. Competitive wholesale prices from a reliable supplier are more beneficial than low prices from an unverified source. Understand the pricing structure for different quantities and inquire about potential discounts for bulk purchases.
4. Supply Chain Reliability: Ensure the supplier has a robust production capacity and efficient logistics to guarantee timely delivery. Disruptions in supply can have significant impacts on production schedules.
5. Technical Support and Communication: A responsive supplier who can offer technical assistance and clear communication is invaluable. Being able to request a quote and receive a prompt, informative response is a good indicator.
