Description

The occurrence of 73466-12-3 Leukotriene A4 methyl ester methyl 4-((2S,3S)-3-((1E,3E,5Z,8Z)-tetradeca-1,3,5,8-tetraenyl)oxiran-2-yl)butanoate is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

73466-12-3 Leukotriene A4 methyl ester methyl 4-((2S,3S)-3-((1E,3E,5Z,8Z)-tetradeca-1,3,5,8-tetraenyl)oxiran-2-yl)butanoate (CAS 73466-12-3), molecular formula C21H32O3 and molecular weight 332.48 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 73466-12-3 Leukotriene A4 methyl ester methyl 4-((2S,3S)-3-((1E,3E,5Z,8Z)-tetradeca-1,3,5,8-tetraenyl)oxiran-2-yl)butanoate (C21H32O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 332.48 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
