Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(5-Bromothiophen-2-yl)-4,4-dimethylpent-1-en-3-one.
1-(5-Bromothiophen-2-yl)-4,4-dimethylpent-1-en-3-one (CAS 1258828-10-2), molecular formula C11H13BrOS and molecular weight 273.19 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(5-Bromothiophen-2-yl)-4,4-dimethylpent-1-en-3-one (C11H13BrOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 1-(5-Bromothiophen-2-yl)-4,4-dimethylpent-1-en-3-one 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.
