Chemical Structure

Pentoxifylline Impurity 21 CAS 14447-27-9 chemical structure

Description

The occurrence of Pentoxifylline Impurity 21 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Pentoxifylline Impurity 21 (CAS 14447-27-9) is a certified pharmaceutical impurity reference standard with the molecular formula C8H16O2 and a molecular weight of 144.21 g/mol.

Based on its molecular formula C8H16O2, Pentoxifylline Impurity 21 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 144.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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 Pentoxifylline Impurity 21 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.
