Chemical Structure
Description
The occurrence of 1-Bromooctadecane-d37 is closely related to deuterium isotope labeling, bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Bromooctadecane-d37 (CAS 187826-28-4), a certified reference material (molecular formula C18D37Br, MW 370.62 g/mol) for analytical method development and quality control.
The molecular framework of 1-Bromooctadecane-d37 (C18D37Br) is characterized by deuterium isotope labeling, bromine substitution, a polycyclic aromatic system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 1-Bromooctadecane-d37 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.
