Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(3-Bromophenoxy)propane-1-sulfonyl chloride.
CATO supplies 3-(3-Bromophenoxy)propane-1-sulfonyl chloride (CAS 1018272-01-9), a certified reference material (molecular formula C9H10BrClO3S, MW 313.60 g/mol) for analytical method development and quality control.
The molecular framework of 3-(3-Bromophenoxy)propane-1-sulfonyl chloride (C9H10BrClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3-(3-Bromophenoxy)propane-1-sulfonyl chloride 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.
