Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-6-[2-bromo-4-(2-ethylhexyl)-4,5-dihydro-5-oxo-6H-thieno[3,2-b]pyrrol-6-ylidene]-4-(2-ethylhexyl)-4,6-dihydro-5H-thieno[3,2-b]pyrrol-5-one.
CATO supplies 2-Bromo-6-[2-bromo-4-(2-ethylhexyl)-4,5-dihydro-5-oxo-6H-thieno[3,2-b]pyrrol-6-ylidene]-4-(2-ethylhexyl)-4,6-dihydro-5H-thieno[3,2-b]pyrrol-5-one (CAS 1147124-49-9), a certified reference material (molecular formula C28H36Br2N2O2S2, MW 656.54 g/mol) for analytical method development and quality control.
Structurally, 2-Bromo-6-[2-bromo-4-(2-ethylhexyl)-4,5-dihydro-5-oxo-6H-thieno[3,2-b]pyrrol-6-ylidene]-4-(2-ethylhexyl)-4,6-dihydro-5H-thieno[3,2-b]pyrrol-5-one (C28H36Br2N2O2S2) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 656.54 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 manufactures 2-Bromo-6-[2-bromo-4-(2-ethylhexyl)-4,5-dihydro-5-oxo-6H-thieno[3,2-b]pyrrol-6-ylidene]-4-(2-ethylhexyl)-4,6-dihydro-5H-thieno[3,2-b]pyrrol-5-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
