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-Methoxy-4,7-dimethyl-3-phenylisobenzofuran-1(3H)-one.
CATO supplies 3-Methoxy-4,7-dimethyl-3-phenylisobenzofuran-1(3H)-one (CAS 72181-93-2), a certified reference material (molecular formula C17H16O3, MW 268.31 g/mol) for analytical method development and quality control.
Structurally, 3-Methoxy-4,7-dimethyl-3-phenylisobenzofuran-1(3H)-one (C17H16O3) contains a steroid core, a hydroxyl group, an ether linkage. 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 268.31 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures 3-Methoxy-4,7-dimethyl-3-phenylisobenzofuran-1(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
