Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-chloro-N-{4-chloro-3-[(dimethylamino)sulfonyl]phenyl}propanamide.
2-chloro-N-{4-chloro-3-[(dimethylamino)sulfonyl]phenyl}propanamide (CAS 929973-64-8), molecular formula C11H14Cl2N2O3S and molecular weight 325.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-chloro-N-{4-chloro-3-[(dimethylamino)sulfonyl]phenyl}propanamide (C11H14Cl2N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-chloro-N-{4-chloro-3-[(dimethylamino)sulfonyl]phenyl}propanamide 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.
