Chemical Structure
Description
2,2'-((6-Amino-5H-imidazo[1,2-b]pyrazol-5-yl)azanediyl)diethanol (CAS 877929-41-4), molecular formula C9H15N5O2 and molecular weight 225.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,2'-((6-Amino-5H-imidazo[1,2-b]pyrazol-5-yl)azanediyl)diethanol (C9H15N5O2) is characterized by an amino-acid-derived structure, 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.
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'-((6-Amino-5H-imidazo[1,2-b]pyrazol-5-yl)azanediyl)diethanol 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.
