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 1-Ethyl-3,5-difluorobenzene.
CATO supplies 1-Ethyl-3,5-difluorobenzene (CAS 117358-52-8), a certified reference material (molecular formula C8H8F2, MW 142.15 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, an aromatic ring system, 1-Ethyl-3,5-difluorobenzene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.15 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), 1-Ethyl-3,5-difluorobenzene 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.
