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 2-{6-[(benzyloxy)methoxy]-3-oxo-3H-xanthen-9-yl}benzoic acid.
CATO supplies 2-{6-[(benzyloxy)methoxy]-3-oxo-3H-xanthen-9-yl}benzoic acid (CAS 277309-46-3), a certified reference material (molecular formula C28H20O6, MW 452.45 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 2-{6-[(benzyloxy)methoxy]-3-oxo-3H-xanthen-9-yl}benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 2-{6-[(benzyloxy)methoxy]-3-oxo-3H-xanthen-9-yl}benzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
