Chemical Structure
Description
As a certified reference material (CRM), 1-Chloro-4-octyne 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-Chloro-4-octyne (CAS 51575-84-9), a certified reference material (molecular formula C8H13Cl, MW 144.64 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, 1-Chloro-4-octyne is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.64 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.
