Description

Compared with other compounds in its class, the molecular weight of 1065.38 g/mol gives 13-{[(3-t-Boc)-2,2-Dimethyl-4S-Phenyl-1,3-Oxazolidin-5R-yl]formyl}-7-O-(2,2,2-trichloroethyl)oxy]carbonyl) Baccatin III distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

13-{[(3-t-Boc)-2,2-Dimethyl-4S-Phenyl-1,3-Oxazolidin-5R-yl]formyl}-7-O-(2,2,2-trichloroethyl)oxy]carbonyl) Baccatin III (CAS 143527-73-5) is a high-purity analytical reference standard with the molecular formula C51H60Cl3NO17 and a molecular weight of 1065.38 g/mol.

The molecular framework of 13-{[(3-t-Boc)-2,2-Dimethyl-4S-Phenyl-1,3-Oxazolidin-5R-yl]formyl}-7-O-(2,2,2-trichloroethyl)oxy]carbonyl) Baccatin III (C51H60Cl3NO17) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
