Chemical Structure
Description
Owing to a steroid core, a hydroxyl group, an ether linkage, 479-33-4 Tetraphenylcyclopentadienone 2,4-Cyclopentadien-1-one, 2,3,4,5-tetraphenyl- AI3-22092 Cyclone EINECS 207-530-3 NSC 2060 Tetracyclon Tetracyclone 2,3,4,5-Tetraphenylcyclopentadienone 2,3,4,5-Tetraphenyl-2,4-cyclopentadienone Tetraphenyl-2,4-cyclopentadien-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 408.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 479-33-4 Tetraphenylcyclopentadienone 2,4-Cyclopentadien-1-one, 2,3,4,5-tetraphenyl- AI3-22092 Cyclone EINECS 207-530-3 NSC 2060 Tetracyclon Tetracyclone 2,3,4,5-Tetraphenylcyclopentadienone 2,3,4,5-Tetraphenyl-2,4-cyclopentadienone Tetraphenyl-2,4-cyclopentadien-1-one (CAS 479-33-4), a certified reference material (molecular formula C29H44O, MW 408.66 g/mol) for analytical method development and quality control.
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.
