Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 890100-57-9 Ethyl 6-(2-chloropyridin-3-yl)-6-oxohexanoate DTXSID60641796.
890100-57-9 Ethyl 6-(2-chloropyridin-3-yl)-6-oxohexanoate DTXSID60641796 (CAS 890100-57-9), molecular formula C13H16ClNO3 and molecular weight 269.72 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 890100-57-9 Ethyl 6-(2-chloropyridin-3-yl)-6-oxohexanoate DTXSID60641796 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
