Duloxetine 2-Naphthalenol Impurity CAS 1346599-09-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Duloxetine 2-Naphthalenol Impurity.

Duloxetine 2-Naphthalenol Impurity (CAS 1346599-09-4) is a certified pharmaceutical impurity reference standard with the molecular formula C18H19NOS and a molecular weight of 297.41 g/mol.

Based on its molecular formula C18H19NOS, Duloxetine 2-Naphthalenol Impurity contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 297.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Duloxetine 2-Naphthalenol Impurity meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
