Chemical Structure

5-Methyl-2-thiophenecarbaldehyde CAS 13679-70-4 chemical structure

Description

The molecular framework of 5-Methyl-2-thiophenecarbaldehyde (C6H6OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, 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).

CATO supplies 5-Methyl-2-thiophenecarbaldehyde (CAS 13679-70-4), a certified reference material (molecular formula C6H6OS, MW 126.18 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
