Ethyl 2-bromo-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate CAS 150108-66-0

Description

As a certified reference material (CRM), Ethyl 2-bromo-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate 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.

Ethyl 2-bromo-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 150108-66-0) is a high-purity analytical reference standard with the molecular formula C11H13BrO2S and a molecular weight of 289.19 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, Ethyl 2-bromo-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 289.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
