Description
CATO manufactures Phenobarbital-D5 (deuterium label on ring) 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.
Phenobarbital-D5 (deuterium label on ring) (CAS 72793-46-5) is a high-purity analytical reference standard with the molecular formula C12H7D5N2O3 and a molecular weight of 237.27 g/mol.
The molecular framework of Phenobarbital-D5 (deuterium label on ring) (C12H7D5N2O3) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
