Chemical Structure
Description
As a certified reference material (CRM), 7-Hydroxy Coumarin-d5 Sulfate Potassium Salt 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.
7-Hydroxy Coumarin-d5 Sulfate Potassium Salt (CAS 1261392-49-7), molecular formula C9HD5O6SK and molecular weight 286.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 7-Hydroxy Coumarin-d5 Sulfate Potassium Salt is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.33 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.
