Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-1-(3-Chlorophenyl)-3-phenylprop-2-en-1-one.
CATO supplies (2E)-1-(3-Chlorophenyl)-3-phenylprop-2-en-1-one (CAS 20426-48-6), a certified reference material (molecular formula C15H11ClO, MW 242.70 g/mol) for analytical method development and quality control.
Structurally, (2E)-1-(3-Chlorophenyl)-3-phenylprop-2-en-1-one (C15H11ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 242.70 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.
