Indometacin Impurity 39 Sodium Salt CAS 5354-81-4

Description

Compared with other compounds in its class, the molecular weight of 238.19 g/mol gives Indometacin Impurity 39 Sodium Salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Indometacin Impurity 39 Sodium Salt (CAS 5354-81-4) is a certified pharmaceutical impurity reference standard with the molecular formula C7H7N2O4SNa and a molecular weight of 238.19 g/mol.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Indometacin Impurity 39 Sodium Salt is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.19 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 Indometacin Impurity 39 Sodium Salt 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.
