    CAS: 260430-02-2 分子式: C25H26N2O4 分子量: 418.49
    Em:510nm ? Fluorescence emission maximum at 510 nm — the wavelength this fluorophore emits after excitation. Use it to pick the right detection filter and avoid channel cross-talk. Ex:492nm ? Fluorescence excitation maximum at 492 nm — the wavelength of light that best excites this fluorophore. Match it to your instrument's laser or filter set for the strongest signal. ≥98%

よくある質問

How do I choose the right Fluorescence Imaging for my synthesis route?
Work backwards from the target structure: identify the bonds you need to form, then pick the Fluorescence Imaging entry whose functional groups, protecting-group pattern, and stereochemistry match. Compare purity, available pack sizes, and stability under your reaction conditions before committing to a route.
What does Fluorescence Imaging cover?
Fluorescence Imaging is a top-level listing in our catalogue. Use the filters and search on the listing page to narrow by the attributes that matter for your work, or browse the neighbouring categories from the main navigation.
What specifications matter most for Fluorescence Imaging?
For Fluorescence Imaging, purity is the headline figure — 95% or better is a common floor for medicinal chemistry, and higher for late-stage steps. Also check isomeric and stereochemical purity, water content for moisture-sensitive groups, storage temperature, and that the pack size matches your scale. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.
What if the Fluorescence Imaging I need is not listed?
Search Fluorescence Imaging by CAS number or SMILES first — close analogs are often listed under a neighbouring subcategory. If nothing matches, custom synthesis and bulk enquiries go to [email protected]. We supply verified businesses, research institutions, universities, and government agencies.
