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 4-(bromomethyl)cyclopent-1-ene.
4-(bromomethyl)cyclopent-1-ene (CAS 80864-33-1), molecular formula C6H9Br and molecular weight 161.04 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, 4-(bromomethyl)cyclopent-1-ene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 161.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 4-(bromomethyl)cyclopent-1-ene 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.
