Phloroglucinol Impurity 63 CAS CATO-C4X-221763

Description

The occurrence of Phloroglucinol Impurity 63 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Phloroglucinol Impurity 63 (CAS CATO-C4X-221763), a pharmacopoeial impurity reference standard (molecular formula C12H16O5, MW 240.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Phloroglucinol Impurity 63 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
