Description

As a certified reference material (CRM), (1S,4E,5'S,6S,6'S,7R,8S,10R,11R,12S,14R,15S,16R,18E,20E,22R,25S,27R,29R)-22-Ethyl-7,11,14,15-tetrahydroxy-6'-((R)-2-hydroxypropyl)-5',6,8,10,12,14,16,29-octamethyl-3',4',5',6'-tetrahydro-2,26-dioxaspiro[bicyclo[23.3.1]nonacosane-27,2'-pyran]-4,18,20-triene-3,9,13-trione 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.

CATO supplies (1S,4E,5'S,6S,6'S,7R,8S,10R,11R,12S,14R,15S,16R,18E,20E,22R,25S,27R,29R)-22-Ethyl-7,11,14,15-tetrahydroxy-6'-((R)-2-hydroxypropyl)-5',6,8,10,12,14,16,29-octamethyl-3',4',5',6'-tetrahydro-2,26-dioxaspiro[bicyclo[23.3.1]nonacosane-27,2'-pyran]-4,18,20-triene-3,9,13-trione (CAS 1404-59-7), a certified reference material (molecular formula C44H72O11, MW 777.04 g/mol) for analytical method development and quality control.

(1S,4E,5'S,6S,6'S,7R,8S,10R,11R,12S,14R,15S,16R,18E,20E,22R,25S,27R,29R)-22-Ethyl-7,11,14,15-tetrahydroxy-6'-((R)-2-hydroxypropyl)-5',6,8,10,12,14,16,29-octamethyl-3',4',5',6'-tetrahydro-2,26-dioxaspiro[bicyclo[23.3.1]nonacosane-27,2'-pyran]-4,18,20-triene-3,9,13-trione (C44H72O11) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
