Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-((9H-Fluorene-2,7-disulfonyl)bis(azanediyl))bis(3-methylbutanoic acid).
CATO supplies 2,2'-((9H-Fluorene-2,7-disulfonyl)bis(azanediyl))bis(3-methylbutanoic acid) (CAS 307941-68-0), a certified reference material (molecular formula C23H28N2O8S2, MW 524.61 g/mol) for analytical method development and quality control.
2,2'-((9H-Fluorene-2,7-disulfonyl)bis(azanediyl))bis(3-methylbutanoic acid) (C23H28N2O8S2) contains a flavonoid core, an amide group, a sulfone 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.
As a certified reference material (CRM), 2,2'-((9H-Fluorene-2,7-disulfonyl)bis(azanediyl))bis(3-methylbutanoic acid) 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.
