Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
rac 3-(1,2,4-Triazol-1-yl)-L-alanine 15N,D2 (CAS 1219176-41-6) is a high-purity analytical reference standard with the molecular formula C5H6D2N3[15N]O2 and a molecular weight of 159.15 g/mol.
The molecular framework of rac 3-(1,2,4-Triazol-1-yl)-L-alanine 15N,D2 (C5H6D2N3[15N]O2) is characterized by deuterium isotope labeling, 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.
As a certified reference material (CRM), rac 3-(1,2,4-Triazol-1-yl)-L-alanine 15N,D2 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.
