4H,5H,6H,7H,8H-Furo[3,2-c]azepine-4-thione CAS 478047-92-6

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies 4H,5H,6H,7H,8H-Furo[3,2-c]azepine-4-thione (CAS 478047-92-6), a certified reference material (molecular formula C8H9NOS, MW 167.23 g/mol) for analytical method development and quality control.

The molecular framework of 4H,5H,6H,7H,8H-Furo[3,2-c]azepine-4-thione (C8H9NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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.

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.
