6-(Fluorescein-5-carboxamido)hexanoic Acid Succinimidyl Ester (>90%) CAS 148356-00-7

Description

Compared with other compounds in its class, the molecular weight of 586.55 g/mol gives 6-(Fluorescein-5-carboxamido)hexanoic Acid Succinimidyl Ester (>90%) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-(Fluorescein-5-carboxamido)hexanoic Acid Succinimidyl Ester (>90%) (CAS 148356-00-7), molecular formula C31H26N2O10 and molecular weight 586.55 g/mol, is a CATO reference standard with documented purity and traceability.

6-(Fluorescein-5-carboxamido)hexanoic Acid Succinimidyl Ester (>90%) (C31H26N2O10) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
