Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 183.20 g/mol gives L(-)-Epinephrine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies L(-)-Epinephrine (CAS 51-43-4), a certified reference material (molecular formula C9H13NO3, MW 183.20 g/mol) for analytical method development and quality control.
The molecular framework of L(-)-Epinephrine (C9H13NO3) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures L(-)-Epinephrine 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.
