Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Di-n-dodecyl-d25-dimethylammonium Bromide (mono-dodecyl-d25) (CAS 918897-30-0), molecular formula C26H31D25NBr and molecular weight 487.80 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Di-n-dodecyl-d25-dimethylammonium Bromide (mono-dodecyl-d25) (C26H31D25NBr) is characterized by deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures Di-n-dodecyl-d25-dimethylammonium Bromide (mono-dodecyl-d25) 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.
