Description
CATO manufactures 1,12-Dichloro-2,5,8,11-tetraoxadodecane 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.
1,12-Dichloro-2,5,8,11-tetraoxadodecane (CAS 16721-83-8) is a high-purity analytical reference standard with the molecular formula C8H16Cl2O4 and a molecular weight of 247.12 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 1,12-Dichloro-2,5,8,11-tetraoxadodecane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.12 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
