Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 169.18 g/mol gives L-Noradrenaline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies L-Noradrenaline (CAS 51-41-2), a certified reference material (molecular formula C8H11NO3, MW 169.18 g/mol) for analytical method development and quality control.
The molecular framework of L-Noradrenaline (C8H11NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures L-Noradrenaline 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.
