Chemical Structure
Description
N-(4-Oxo-5,6,7,8-tetrahydro-4H-thiazolo[5,4-c]azepin-2-yl)-2-(6-oxopyridazin-1(6H)-yl)acetamide (CAS 1797698-63-5) is a high-purity analytical reference standard with the molecular formula C13H13N5O3S and a molecular weight of 319.34 g/mol.
The molecular framework of N-(4-Oxo-5,6,7,8-tetrahydro-4H-thiazolo[5,4-c]azepin-2-yl)-2-(6-oxopyridazin-1(6H)-yl)acetamide (C13H13N5O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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.
