Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-chlorothieno[3,2-b]pyridine-2-carbaldehyde (CAS 387819-41-2), molecular formula C8H12ClNOS and molecular weight 205.70 g/mol, is a CATO reference standard with documented purity and traceability.
7-chlorothieno[3,2-b]pyridine-2-carbaldehyde (C8H12ClNOS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
