Chemical Structure

Hydroxyethyl Salicylate EP Impurity C CAS 13461-41-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 226.23 g/mol gives Hydroxyethyl Salicylate EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Hydroxyethyl Salicylate EP Impurity C (CAS 13461-41-1), a pharmacopoeial impurity reference standard (molecular formula C11H14O5, MW 226.23 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Hydroxyethyl Salicylate EP Impurity C (C11H14O5) 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).

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), Hydroxyethyl Salicylate EP Impurity C 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.
