Choline-1,1,2,2-d4 Bromide (CAS 285979-69-3), molecular formula C5H10D4NOBr and molecular weight 188.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Choline-1,1,2,2-d4 Bromide (C5H10D4NOBr) is characterized by deuterium isotope labeling, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures Choline-1,1,2,2-d4 Bromide 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.
