Chemical Structure

Atorvastatin Impurity 38 CAS 1105067-89-7 chemical structure

Description

The occurrence of Atorvastatin Impurity 38 is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Atorvastatin Impurity 38 (CAS 1105067-89-7), a pharmacopoeial impurity reference standard (molecular formula C14H27NO4, MW 273.37 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H27NO4, Atorvastatin Impurity 38 contains an amide group, 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 273.37 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 Atorvastatin Impurity 38 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.
