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 QPX7728.
CATO supplies QPX7728 (CAS 2170834-63-4), a certified reference material (molecular formula C10H8BFO4, MW 221.98 g/mol) for analytical method development and quality control.
Structurally, QPX7728 (C10H8BFO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.5, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 221.98 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.
As a certified reference material (CRM), QPX7728 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.
