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 1-Chloro-4-ethoxy-1,1-difluorobut-3-en-2-one.
1-Chloro-4-ethoxy-1,1-difluorobut-3-en-2-one (CAS 170118-79-3) is a high-purity analytical reference standard with the molecular formula C6H7ClF2O2 and a molecular weight of 184.57 g/mol.
Structurally, 1-Chloro-4-ethoxy-1,1-difluorobut-3-en-2-one (C6H7ClF2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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 184.57 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.
