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 7H,14H-Pyrazino[1,2-b:4,5-b]diindazole-7,14-dione.
7H,14H-Pyrazino[1,2-b:4,5-b]diindazole-7,14-dione (CAS 115660-68-9), molecular formula C16H8N4O2 and molecular weight 288.26 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 7H,14H-Pyrazino[1,2-b:4,5-b]diindazole-7,14-dione (C16H8N4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 288.26 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.
