Chemical Structure

Ethyl 8-(2-chloropyridin-3-yl)-8-oxooctanoate CAS 890100-61-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 8-(2-chloropyridin-3-yl)-8-oxooctanoate.

Ethyl 8-(2-chloropyridin-3-yl)-8-oxooctanoate (CAS 890100-61-5), molecular formula C15H20ClNO3 and molecular weight 297.78 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Ethyl 8-(2-chloropyridin-3-yl)-8-oxooctanoate (C15H20ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 297.78 g/mol, it falls into the medium-molecular-weight range. 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.
