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.

CATO supplies (3R,5S,6E)-rel-7-[4-(4-Fluorophenyl)-5-(hydroxymethyl)-2,6-bis(1-methylethyl)-3-pyridinyl]-3,5-dihydroxy-6-heptenoic Acid Methyl Ester 124863-87-2 Methyl rel-(E)-7-[2,6-Diisopropyl-4-(4-fluorophenyl)-5-hydroxymethylpyridinyl]-3,5-dihydroxy-6-heptenoate (CAS 124863-87-2), a certified reference material (molecular formula C26H34FNO5, MW 459.55 g/mol) for analytical method development and quality control.

The molecular framework of (3R,5S,6E)-rel-7-[4-(4-Fluorophenyl)-5-(hydroxymethyl)-2,6-bis(1-methylethyl)-3-pyridinyl]-3,5-dihydroxy-6-heptenoic Acid Methyl Ester 124863-87-2 Methyl rel-(E)-7-[2,6-Diisopropyl-4-(4-fluorophenyl)-5-hydroxymethylpyridinyl]-3,5-dihydroxy-6-heptenoate (C26H34FNO5) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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.
