Ethyl 2-bromo-5-formyl-3-thiophenecarboxylate CAS 2110781-56-9

Description

The occurrence of Ethyl 2-bromo-5-formyl-3-thiophenecarboxylate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 2-bromo-5-formyl-3-thiophenecarboxylate (CAS 2110781-56-9) is a high-purity analytical reference standard with the molecular formula C8H7BrO3S and a molecular weight of 263.11 g/mol.

The molecular framework of Ethyl 2-bromo-5-formyl-3-thiophenecarboxylate (C8H7BrO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Ethyl 2-bromo-5-formyl-3-thiophenecarboxylate 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.
