(E)-3,4-dihydronaphthalen-1(2H)-one O-phenylsulfonyl oxime CAS 145609-82-1 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 (E)-3,4-dihydronaphthalen-1(2H)-one O-phenylsulfonyl oxime.

(E)-3,4-dihydronaphthalen-1(2H)-one O-phenylsulfonyl oxime (CAS 145609-82-1), molecular formula C16H15NO3S and molecular weight 301.36 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-3,4-dihydronaphthalen-1(2H)-one O-phenylsulfonyl oxime (C16H15NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
