Methyl 5-bromo-4-chloro-3-hydroxythiophene-2-carboxylate CAS 1095124-55-2

Description

Compared with other compounds in its class, the molecular weight of 271.52 g/mol gives Methyl 5-bromo-4-chloro-3-hydroxythiophene-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 5-bromo-4-chloro-3-hydroxythiophene-2-carboxylate (CAS 1095124-55-2), molecular formula C6H4BrClO3S and molecular weight 271.52 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, Methyl 5-bromo-4-chloro-3-hydroxythiophene-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 271.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
