Chemical Structure
Description
1,11-Difluoro-undecane (CAS 1828-07-5), molecular formula C11H22F2 and molecular weight 192.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, 1,11-Difluoro-undecane is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 192.29 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.
CATO manufactures 1,11-Difluoro-undecane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
