Metaxalone Impurity 3 CAS CATO-C4X-30053 chemical structure

Description

CATO manufactures Metaxalone Impurity 3 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.

Metaxalone Impurity 3 (CAS CATO-C4X-30053) is a certified pharmaceutical impurity reference standard with the molecular formula C11H16O3 and a molecular weight of 196.24 g/mol.

Structurally, Metaxalone Impurity 3 (C11H16O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 196.24 g/mol, it falls into the medium-molecular-weight range. 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.
