Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-Chloro-4-(pent-4-en-1-yl)benzene (CAS 134831-42-8), a certified reference material (molecular formula C11H13Cl, MW 180.67 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, an aromatic ring system, 1-Chloro-4-(pent-4-en-1-yl)benzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 180.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), 1-Chloro-4-(pent-4-en-1-yl)benzene 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.
