CATO supplies (R)-2-Amino-2-((R)-3-oxoisoxazolidin-5-yl)acetic acid (CAS 2644-49-7), a certified reference material (molecular formula C5H8N2O4, MW 160.13 g/mol) for analytical method development and quality control.
The molecular framework of (R)-2-Amino-2-((R)-3-oxoisoxazolidin-5-yl)acetic acid (C5H8N2O4) is characterized by a carbohydrate-derived structure, an amide group. 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), (R)-2-Amino-2-((R)-3-oxoisoxazolidin-5-yl)acetic 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.
