Chemical Structure

Phloroglucinol Impurity 4 CAS 871893-76-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 256.21 g/mol gives Phloroglucinol Impurity 4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Phloroglucinol Impurity 4 (CAS 871893-76-4), a certified reference material (molecular formula C11H12O7, MW 256.21 g/mol) for analytical method development and quality control.

The molecular framework of Phloroglucinol Impurity 4 (C11H12O7) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 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.

As a certified reference material (CRM), Phloroglucinol Impurity 4 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.
