Chemical Structure

Torasemide Impurity 17 CAS 5602-90-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Torasemide Impurity 17.

Torasemide Impurity 17 (CAS 5602-90-4) is a certified pharmaceutical impurity reference standard with the molecular formula C5H11NO2 and a molecular weight of 117.15 g/mol.

Based on its molecular formula C5H11NO2, Torasemide Impurity 17 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 117.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 Torasemide Impurity 17 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.
