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 3-(4-Chlorophenoxy)-3-(4-methoxyphenoxy)-3H-diazirine.
3-(4-Chlorophenoxy)-3-(4-methoxyphenoxy)-3H-diazirine (CAS 651306-57-9), molecular formula C14H11ClN2O3 and molecular weight 290.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(4-Chlorophenoxy)-3-(4-methoxyphenoxy)-3H-diazirine (C14H11ClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
