Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(2H-1,3-Benzodioxol-5-yl)-2-[(E)-2-(4-chlorophenyl)ethenyl]-5H-indeno[1,2-b]pyridin-5-one.
CATO supplies 4-(2H-1,3-Benzodioxol-5-yl)-2-[(E)-2-(4-chlorophenyl)ethenyl]-5H-indeno[1,2-b]pyridin-5-one (CAS 866136-01-8), a certified reference material (molecular formula C27H16ClNO3, MW 437.87 g/mol) for analytical method development and quality control.
Structurally, 4-(2H-1,3-Benzodioxol-5-yl)-2-[(E)-2-(4-chlorophenyl)ethenyl]-5H-indeno[1,2-b]pyridin-5-one (C27H16ClNO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 437.87 g/mol, it falls into the moderately-high-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.
