Description
CATO supplies 4,5-Dichlorothiophene-3-carbaldehyde (CAS 61200-59-7), a certified reference material (molecular formula C5H2Cl2OS, MW 181.04 g/mol) for analytical method development and quality control.
Based on its molecular formula C5H2Cl2OS, 4,5-Dichlorothiophene-3-carbaldehyde contains sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 181.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
