Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Thiophen-3-yl)butanal.
CATO supplies 4-(Thiophen-3-yl)butanal (CAS 1343157-37-8), a certified reference material (molecular formula C8H10OS, MW 154.23 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H10OS, 4-(Thiophen-3-yl)butanal contains sulfur-containing functionality, 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 154.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
