As a certified reference material (CRM), L-Tryptophan-13C11-15N2 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.
L-Tryptophan-13C11-15N2 (CAS 202406-50-6), molecular formula [13C]11H12[15N]2O2 and molecular weight 217.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of L-Tryptophan-13C11-15N2 ([13C]11H12[15N]2O2) is characterized by an organic framework. 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.
