Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,5-Bis(Chloromethyl)-2,4-Diisopropylbenzene.
CATO supplies 1,5-Bis(Chloromethyl)-2,4-Diisopropylbenzene (CAS 7188-14-9), a certified reference material (molecular formula C14H20Cl2, MW 259.21 g/mol) for analytical method development and quality control.
The molecular framework of 1,5-Bis(Chloromethyl)-2,4-Diisopropylbenzene (C14H20Cl2) is characterized by chlorine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 1,5-Bis(Chloromethyl)-2,4-Diisopropylbenzene 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.
