Two Purity Grades for Different Application Needs
To meet diverse performance and budget requirements, Nichwell supplies pigment red311 in two distinct purity grades:
- Standard Grade (Purity ≥92%): A cost-effective powerhouse for general fluorescent polymer compounding, security offset/inkjet inks, and specialty industrial coatings.
- Optical Grade (Purity ≥95%): Extensively refined for Luminescent Solar Concentrators (LSC), transparent PMMA/PS optics, and optoelectronic research where maximum fluorescence quantum yield (ФF) and zero optical quenching are non-negotiable.
Note: This molecular structure is also widely known in scientific literature and industrial applications under CAS 123174-58-3. Our standard commercial grade is supplied under CAS 112100-07-9.
Applications of Perylene Red 311 (CAS: 112100-07-9)
Luminescent Solar Concentrators (LSC) & Photovoltaics
Leveraging its large Stokes shift and outstanding photostability, our PR 311 is widely adopted in Building-Integrated Photovoltaics (BIPV), transparent solar windows, and agricultural greenhouse films.
High-Security & Specialty Inks
Provides a sharply defined, machine-readable fluorescent signature under UV light. Ideal for banknote authentication, tax stamps, brand protection labels, and UV-fluorescent dyes.
Organic Electronics & OLEDs
Functions as a highly stable n-type organic semiconductor material for red emissive layers in OLEDs and acceptor materials in Organic Photovoltaics.

FAQ
Q1: Is Nichwell PR 311 a direct drop-in replacement for Lumogen Red 305?
A1: Yes. Both share the exact same chemical structure and CAS registry (112100-07-9). Our product is engineered to match the spectral specifications, lightfastness, and thermal stability of the benchmark, requiring zero to minimal formulation adjustments.
Q2: How can I verify the batch-to-batch consistency?
A2: We operate under strict ISO-certified quality management. We provide comprehensive Certificates of Analysis (COA) detailing purity, melting point, and λmaxλmax with every order. Pre-shipment samples are also available for commercial container orders.
Q3: Can I get a testing sample before committing to a commercial order?
A3: Absolutely. We provide 10g-50g evaluation samples for qualified R&D and procurement professionals.
Q4: What are your packaging options and MOQs?
A4: Sample MOQ starts at just 10g. Commercial packaging is available in 1kg, 5kg, and 10kg heavy-duty cartons/drums. Custom protective packaging is available upon request.
