Chemical Structure

6-[Fluorescein-5 (6)-carboxamido]hexanoic acid<I>N</I>-hydroxysuccinimide ester CAS 114616-31-8 chemical structure

Description

The molecular framework of 6-[Fluorescein-5 (6)-carboxamido]hexanoic acid<I>N</I>-hydroxysuccinimide ester (C31H44N2O10) is characterized by a nitrogen-containing heterocyclic scaffold, 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).

6-[Fluorescein-5 (6)-carboxamido]hexanoic acid<I>N</I>-hydroxysuccinimide ester (CAS 114616-31-8) is a high-purity analytical reference standard with the molecular formula C31H44N2O10 and a molecular weight of 604.70 g/mol.

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), 6-[Fluorescein-5 (6)-carboxamido]hexanoic acid<I>N</I>-hydroxysuccinimide ester 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.
