5-propylthiophene-2-carbaldehyde CAS 35250-76-1

Description

Compared with other compounds in its class, the molecular weight of 158.26 g/mol gives 5-propylthiophene-2-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-propylthiophene-2-carbaldehyde (CAS 35250-76-1), molecular formula C8H14OS and molecular weight 158.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-propylthiophene-2-carbaldehyde (C8H14OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage. 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.

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.

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.
