Chemical Structure
Description
The occurrence of 1,2-Dihydro-1,2,4,5-tetrazine-3,6-dicarboxylic acid is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,2-Dihydro-1,2,4,5-tetrazine-3,6-dicarboxylic acid (CAS 3787-09-5), a certified reference material (molecular formula C4H4N4O4, MW 172.10 g/mol) for analytical method development and quality control.
The molecular framework of 1,2-Dihydro-1,2,4,5-tetrazine-3,6-dicarboxylic acid (C4H4N4O4) is characterized by a carbohydrate-derived structure, an amide group. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
