Description
As a certified reference material (CRM), (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-3-(acetamidothio)-3-methylbutanoic acid 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.
(R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-3-(acetamidothio)-3-methylbutanoic acid (CAS 1246647-73-3), molecular formula C23H26N2O5S and molecular weight 442.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (R)-2-((((9H-Fluoren-9-yl)methoxy)carbonyl)(methyl)amino)-3-(acetamidothio)-3-methylbutanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 442.53 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.
