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 Methyl (6-chloro-7-methoxy-4-methyl-2-oxo-2H-chromen-3-yl)acetate.
CATO supplies Methyl (6-chloro-7-methoxy-4-methyl-2-oxo-2H-chromen-3-yl)acetate (CAS 919751-92-1), a certified reference material (molecular formula C14H13ClO5, MW 296.70 g/mol) for analytical method development and quality control.
The molecular framework of Methyl (6-chloro-7-methoxy-4-methyl-2-oxo-2H-chromen-3-yl)acetate (C14H13ClO5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Methyl (6-chloro-7-methoxy-4-methyl-2-oxo-2H-chromen-3-yl)acetate 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.
