Description
As a certified reference material (CRM), 3-Methoxy-2,5,8,11,14,17,20,23,26-nonaoxaoctacosan-28-yl 4-methylbenzenesulfonate 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.
3-Methoxy-2,5,8,11,14,17,20,23,26-nonaoxaoctacosan-28-yl 4-methylbenzenesulfonate (CAS 2874309-18-7), molecular formula C27H48O13S and molecular weight 612.73 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-Methoxy-2,5,8,11,14,17,20,23,26-nonaoxaoctacosan-28-yl 4-methylbenzenesulfonate is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 612.73 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
