Chemical Structure
Description
As a certified reference material (CRM), 1-(Bromomethyl)-4-methylcyclohexane 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.
CATO supplies 1-(Bromomethyl)-4-methylcyclohexane (CAS 21857-32-9), a certified reference material (molecular formula C8H15Br, MW 191.11 g/mol) for analytical method development and quality control.
The molecular framework of 1-(Bromomethyl)-4-methylcyclohexane (C8H15Br) is characterized by bromine substitution. 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. 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.
