Chemical Structure

Roflumilast Impurity 27 CAS 74976-40-2 chemical structure

Description

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 process- or degradation-related impurity, Roflumilast Impurity 27 (CAS 74976-40-2, C8H14O) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Based on its molecular formula C8H14O, Roflumilast Impurity 27 contains a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 126.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

CATO manufactures Roflumilast Impurity 27 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.
