Chemical Structure
Description
2-Dodecanamido-5-guanidinopentanoic acid (CAS 133849-37-3), molecular formula C18H36N4O3 and molecular weight 356.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Dodecanamido-5-guanidinopentanoic acid (C18H36N4O3) is characterized by an amide group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 2-Dodecanamido-5-guanidinopentanoic 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.
