Chemical Structure
Description
As a certified reference material (CRM), (3S)-3-(4-hydroxy-1-naphthalenyl)-3-(5-hydroxy-1-naphthalenyl)-1-isobenzofuranone (3S)-3-(4-oxidanylnaphthalen-1-yl)-3-(5-oxidanylnaphthalen-1-yl)-2-benzofuran-1-one 596-01-0 A832379 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 (3S)-3-(4-hydroxy-1-naphthalenyl)-3-(5-hydroxy-1-naphthalenyl)-1-isobenzofuranone (3S)-3-(4-oxidanylnaphthalen-1-yl)-3-(5-oxidanylnaphthalen-1-yl)-2-benzofuran-1-one 596-01-0 A832379 (CAS 596-01-0), a certified reference material (molecular formula C28H44O4, MW 444.65 g/mol) for analytical method development and quality control.
Owing to a steroid core, a hydroxyl group, an ether linkage, (3S)-3-(4-hydroxy-1-naphthalenyl)-3-(5-hydroxy-1-naphthalenyl)-1-isobenzofuranone (3S)-3-(4-oxidanylnaphthalen-1-yl)-3-(5-oxidanylnaphthalen-1-yl)-2-benzofuran-1-one 596-01-0 A832379 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 444.65 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.
