Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 120.11 g/mol gives L-Threonine-15N distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies L-Threonine-15N (CAS 80681-09-0), a certified reference material (molecular formula C4H9[15N]O3, MW 120.11 g/mol) for analytical method development and quality control.
The molecular framework of L-Threonine-15N (C4H9[15N]O3) 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), L-Threonine-15N 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.
