Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
DL-Norepinephrine-d6 (CAS CATO-CCAD303845), molecular formula C8H5D6NO3 and molecular weight 175.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of DL-Norepinephrine-d6 (C8H5D6NO3) is characterized by deuterium isotope labeling, 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
