2-Bromoethanethiol CAS 6982-46-3 chemical structure

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.

2-Bromoethanethiol (CAS 6982-46-3), molecular formula C2H5BrS and molecular weight 141.03 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C2H5BrS, 2-Bromoethanethiol contains sulfur-containing functionality, bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 141.03 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.

As a certified reference material (CRM), 2-Bromoethanethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
