Chemical Structure
Description
Ethyl(E)-2-chloro-2-(hydroxyimino)acetate (CAS 861135-87-7) is a high-purity analytical reference standard with the molecular formula C4H6ClNO3 and a molecular weight of 151.55 g/mol.
Structurally, Ethyl(E)-2-chloro-2-(hydroxyimino)acetate (C4H6ClNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 151.55 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.
