1-(3-Bromothiophen-2-yl)-2-((1-cyclopropyl-1h-tetrazol-5-yl)thio)ethan-1-one CAS 1156230-41-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3-Bromothiophen-2-yl)-2-((1-cyclopropyl-1h-tetrazol-5-yl)thio)ethan-1-one.

1-(3-Bromothiophen-2-yl)-2-((1-cyclopropyl-1h-tetrazol-5-yl)thio)ethan-1-one (CAS 1156230-41-9) is a high-purity analytical reference standard with the molecular formula C10H9BrN4OS2 and a molecular weight of 345.24 g/mol.

The molecular framework of 1-(3-Bromothiophen-2-yl)-2-((1-cyclopropyl-1h-tetrazol-5-yl)thio)ethan-1-one (C10H9BrN4OS2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

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.
