Description
CATO manufactures 1-Phenyl-2,5,8,11,14,17-hexaoxanonadecan-19-oic acid 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-Phenyl-2,5,8,11,14,17-hexaoxanonadecan-19-oic acid (CAS 872409-91-1), molecular formula C19H30O8 and molecular weight 386.44 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1-Phenyl-2,5,8,11,14,17-hexaoxanonadecan-19-oic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 386.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
