Loxoprofen Impurity 129 CAS 15585-44-1 chemical structure

Description

CATO manufactures Loxoprofen Impurity 129 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.

Loxoprofen Impurity 129 (CAS 15585-44-1) is a certified pharmaceutical impurity reference standard with the molecular formula C9H14O3 and a molecular weight of 170.21 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Loxoprofen Impurity 129 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 170.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
