Chemical Structure

5-bromo-1H-thieno[2,3-c]pyrazole CAS 1511732-68-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 5-bromo-1H-thieno[2,3-c]pyrazole (CAS 1511732-68-5), a certified reference material (molecular formula C5H9BrN2S, MW 209.11 g/mol) for analytical method development and quality control.

Based on its molecular formula C5H9BrN2S, 5-bromo-1H-thieno[2,3-c]pyrazole contains a nitrile group, sulfur-containing functionality, bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 209.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
