Bromfenac Impurity 36 CAS CATO-C4X-200236

Description

The occurrence of Bromfenac Impurity 36 is closely related to a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Bromfenac Impurity 36 (CAS CATO-C4X-200236), a pharmacopoeial impurity reference standard (molecular formula C30H19Br2N2NaO7, MW 702.28 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, Bromfenac Impurity 36 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 702.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Bromfenac Impurity 36 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.
