Chemical Structure

Norepinephrine Impurity 103 CAS 102743-86-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 197.23 g/mol gives Norepinephrine Impurity 103 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Norepinephrine Impurity 103 (CAS 102743-86-2) is a certified pharmaceutical impurity reference standard with the molecular formula C10H15NO3 and a molecular weight of 197.23 g/mol.

Norepinephrine Impurity 103 (C10H15NO3) contains an amino-acid-derived structure, 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. 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 Norepinephrine Impurity 103 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.
