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.
(2S)-2-(4-(2-(2,4-Diamino-6,7-dihydro-5H-cyclopenta[d]pyrimidin-5-yl)ethyl)benzamido)pentanedioic acid (CAS 149325-93-9), molecular formula C21H25N5O5 and molecular weight 427.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2S)-2-(4-(2-(2,4-Diamino-6,7-dihydro-5H-cyclopenta[d]pyrimidin-5-yl)ethyl)benzamido)pentanedioic acid (C21H25N5O5) is characterized by a flavonoid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), (2S)-2-(4-(2-(2,4-Diamino-6,7-dihydro-5H-cyclopenta[d]pyrimidin-5-yl)ethyl)benzamido)pentanedioic 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.
