Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, EGF816 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 495.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
EGF816 (CAS 1508250-71-2), molecular formula C26H31ClN6O2 and molecular weight 495.02 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
