[1,2,5]Selenadiazolo[3,4-d]pyrimidin-7(3H)-one CAS 7698-94-4

Description

The occurrence of [1,2,5]Selenadiazolo[3,4-d]pyrimidin-7(3H)-one is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

[1,2,5]Selenadiazolo[3,4-d]pyrimidin-7(3H)-one (CAS 7698-94-4), molecular formula C5H12NO5P and molecular weight 197.13 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [1,2,5]Selenadiazolo[3,4-d]pyrimidin-7(3H)-one (C5H12NO5P) is characterized by a carbohydrate-derived structure, an amide group, a phosphate ester 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.
