Description
Ammoxetine Impurity 11 (CAS CATO-C4X-335711) is a certified pharmaceutical impurity reference standard with the molecular formula C7H6ClFO2 and a molecular weight of 176.57 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, Ammoxetine Impurity 11 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures Ammoxetine Impurity 11 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.
