Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Bromofuran-2,4(3H,5H)-dione.
CATO supplies 3-Bromofuran-2,4(3H,5H)-dione (CAS 1192-50-3), a certified reference material (molecular formula C4H3BrO3, MW 178.97 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 3-Bromofuran-2,4(3H,5H)-dione is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.97 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.
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.
As a certified reference material (CRM), 3-Bromofuran-2,4(3H,5H)-dione 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.
