CATO supplies 2-(6,7-Dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-3-yl)acetic acid (CAS 937677-67-3), a certified reference material (molecular formula C7H9N3O2, MW 167.17 g/mol) for analytical method development and quality control.
The molecular framework of 2-(6,7-Dihydro-5H-pyrrolo[2,1-c][1,2,4]triazol-3-yl)acetic acid (C7H9N3O2) 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.
