Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 3-(5-bromothiophen-2-yl)acrylate.
CATO supplies Ethyl 3-(5-bromothiophen-2-yl)acrylate (CAS 108373-19-9), a certified reference material (molecular formula C9H9BrO2S, MW 261.14 g/mol) for analytical method development and quality control.
Structurally, Ethyl 3-(5-bromothiophen-2-yl)acrylate (C9H9BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 261.14 g/mol, it falls into the medium-molecular-weight range. 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.
CATO manufactures Ethyl 3-(5-bromothiophen-2-yl)acrylate 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.
