7-O-(Trifluoroacetyl) Baccatin III CAS 158811-19-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-O-(Trifluoroacetyl) Baccatin III.

7-O-(Trifluoroacetyl) Baccatin III (CAS 158811-19-9) is a high-purity analytical reference standard with the molecular formula C32H37F3O13S and a molecular weight of 718.69 g/mol.

Structurally, 7-O-(Trifluoroacetyl) Baccatin III (C32H37F3O13S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 718.69 g/mol, it falls into the 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.

As a certified reference material (CRM), 7-O-(Trifluoroacetyl) Baccatin III meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
