4-((4R)-2-(((9H-fluoren-9-yl)methoxy)carbonyl)-4-methyl-1,3-dioxan-2-yl)benzoic acid CAS 205109-16-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((4R)-2-(((9H-fluoren-9-yl)methoxy)carbonyl)-4-methyl-1,3-dioxan-2-yl)benzoic acid.

CATO supplies 4-((4R)-2-(((9H-fluoren-9-yl)methoxy)carbonyl)-4-methyl-1,3-dioxan-2-yl)benzoic acid (CAS 205109-16-6), a certified reference material (molecular formula C27H24O6, MW 444.48 g/mol) for analytical method development and quality control.

The molecular framework of 4-((4R)-2-(((9H-fluoren-9-yl)methoxy)carbonyl)-4-methyl-1,3-dioxan-2-yl)benzoic acid (C27H24O6) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
