Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N,n-bis-(2-chloroethyl)-carbamic acid phenyl ester (CAS 13249-63-3), molecular formula C11H13Cl2NO2 and molecular weight 262.13 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N,n-bis-(2-chloroethyl)-carbamic acid phenyl ester (C11H13Cl2NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), N,n-bis-(2-chloroethyl)-carbamic acid phenyl ester meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
