Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzo[e][1,2,4]triazolo[5,1-c][1,2,4]triazin-6-ol.

Benzo[e][1,2,4]triazolo[5,1-c][1,2,4]triazin-6-ol (CAS 1374509-39-3), molecular formula C8H5N5O and molecular weight 187.16 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Benzo[e][1,2,4]triazolo[5,1-c][1,2,4]triazin-6-ol (C8H5N5O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 187.16 g/mol, it falls into the medium-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.
