As a certified reference material (CRM), 4,4',4''-(Benzene-1,3,5-triyl)tris(2-methylbut-3-yn-2-ol) 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 4,4',4''-(Benzene-1,3,5-triyl)tris(2-methylbut-3-yn-2-ol) (CAS 105405-52-5), a certified reference material (molecular formula C21H24O3, MW 324.41 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, 4,4',4''-(Benzene-1,3,5-triyl)tris(2-methylbut-3-yn-2-ol) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 324.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
