5-(2-Hexyldecyl)thiophene-2-carbaldehyde CAS 1363332-57-3

Description

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.

5-(2-Hexyldecyl)thiophene-2-carbaldehyde (CAS 1363332-57-3), molecular formula C21H36OS and molecular weight 336.57 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-(2-Hexyldecyl)thiophene-2-carbaldehyde is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.57 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.
