Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Methyl 3-oxo-2,5,6,7-tetrahydro-3H-pyrrolo-[2,1-c][1,2,4]triazole-5-carboxylate (CAS 1934243-45-4), a certified reference material (molecular formula C7H9N3O3, MW 183.16 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-oxo-2,5,6,7-tetrahydro-3H-pyrrolo-[2,1-c][1,2,4]triazole-5-carboxylate (C7H9N3O3) 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.
As a certified reference material (CRM), Methyl 3-oxo-2,5,6,7-tetrahydro-3H-pyrrolo-[2,1-c][1,2,4]triazole-5-carboxylate 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.
