5-Isobutoxy-3-methoxythiophene-2-carboxylic acid CAS 1774902-17-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Isobutoxy-3-methoxythiophene-2-carboxylic acid.

5-Isobutoxy-3-methoxythiophene-2-carboxylic acid (CAS 1774902-17-8), molecular formula C10H14O4S and molecular weight 230.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H14O4S, 5-Isobutoxy-3-methoxythiophene-2-carboxylic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 230.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
