Chemical Structure
Description
5-Methyl-4-((o-tolyloxy)methyl)thiophene-2-carbaldehyde (CAS 869950-30-1) is a high-purity analytical reference standard with the molecular formula C14H14O2S and a molecular weight of 246.32 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 5-Methyl-4-((o-tolyloxy)methyl)thiophene-2-carbaldehyde is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 5-Methyl-4-((o-tolyloxy)methyl)thiophene-2-carbaldehyde under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
