Chemical Structure

Salbutamol Impurity 129 CAS 18910-69-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 253.34 g/mol gives Salbutamol Impurity 129 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Salbutamol Impurity 129 (CAS 18910-69-5) is a certified pharmaceutical impurity reference standard with the molecular formula C14H23NO3 and a molecular weight of 253.34 g/mol.

Salbutamol Impurity 129 (C14H23NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 Salbutamol Impurity 129 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.
