Eugenol EP Impurity D CAS 501-92-8 chemical structure

Description

CATO manufactures Eugenol EP Impurity D under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies Eugenol EP Impurity D (CAS 501-92-8), a pharmacopoeial impurity reference standard (molecular formula C9H10O, MW 134.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H10O, Eugenol EP Impurity D contains a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 134.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
