Chemical Structure
Description
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.
2-Debenzoyl Paclitaxel 2-Pentanoate (CAS 213767-22-7) is a high-purity analytical reference standard with the molecular formula C45H55NO14 and a molecular weight of 833.92 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-Debenzoyl Paclitaxel 2-Pentanoate is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 833.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
