Chemical Structure
Description
CATO supplies 1-Phenyl-2-((1-phenyl-1h-tetrazol-5-yl)thio)ethan-1-one (CAS 25746-67-2), a certified reference material (molecular formula C15H12N4OS, MW 296.35 g/mol) for analytical method development and quality control.
Structurally, 1-Phenyl-2-((1-phenyl-1h-tetrazol-5-yl)thio)ethan-1-one (C15H12N4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 296.35 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.
