Chemical Structure

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-methyldodec-11-enoic acid CAS 1640968-91-7 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.

(S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-methyldodec-11-enoic acid (CAS 1640968-91-7), molecular formula C28H35NO4 and molecular weight 449.58 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-methyldodec-11-enoic acid (C28H35NO4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 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).

CATO manufactures (S)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)-2-methyldodec-11-enoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
