Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 405.45 g/mol gives 21-Bromohenicosanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 21-Bromohenicosanoic acid (CAS 855953-37-6), a certified reference material (molecular formula C21H41BrO2, MW 405.45 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 21-Bromohenicosanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 21-Bromohenicosanoic acid 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.
