Description

2,2,2-trifluoro-N-[(7S)-10-hydroxy-1,2,3-trimethoxy-9-oxo-6,7-dihydro-5H-benzo[a]heptalen-7-yl]acetamide 71295-34-6 Acetamide, 2,2,2-trifluoro-N-(5,6,7,9-tetrahydro-10-hydroxy-1,2,3-trimethoxy-9-oxobenzo[a]heptalen-7-yl)-, (S)- Colchiceine analog N-Trifluoroacetyl-N-deacetylcolchiceine (CAS 71295-34-6) is a high-purity analytical reference standard with the molecular formula C21H20F3NO6 and a molecular weight of 439.38 g/mol.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2,2,2-trifluoro-N-[(7S)-10-hydroxy-1,2,3-trimethoxy-9-oxo-6,7-dihydro-5H-benzo[a]heptalen-7-yl]acetamide 71295-34-6 Acetamide, 2,2,2-trifluoro-N-(5,6,7,9-tetrahydro-10-hydroxy-1,2,3-trimethoxy-9-oxobenzo[a]heptalen-7-yl)-, (S)- Colchiceine analog N-Trifluoroacetyl-N-deacetylcolchiceine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 439.38 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.

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.
