3H,4H-pyrrolo[1,2-d][1,2,4]triazin-4-one CAS 37526-43-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3H,4H-pyrrolo[1,2-d][1,2,4]triazin-4-one.

CATO supplies 3H,4H-pyrrolo[1,2-d][1,2,4]triazin-4-one (CAS 37526-43-5), a certified reference material (molecular formula C6H11N3O, MW 141.17 g/mol) for analytical method development and quality control.

Structurally, 3H,4H-pyrrolo[1,2-d][1,2,4]triazin-4-one (C6H11N3O) contains an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 141.17 g/mol, it falls into the low-molecular-weight range. 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.
