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 6-Bromo-8-chloro-4,4-dimethylthiochroman (CAS 1350761-67-9), a certified reference material (molecular formula C11H12BrClS, MW 291.63 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, chlorine/bromine substitution, an aromatic ring system, 6-Bromo-8-chloro-4,4-dimethylthiochroman is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 6-Bromo-8-chloro-4,4-dimethylthiochroman 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.
