Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Heptanoic-5,5,6,6,7,7,7-d7 Acid (CAS 1219802-86-4) is a high-purity analytical reference standard with the molecular formula C7H7D7O2 and a molecular weight of 137.23 g/mol.
Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Heptanoic-5,5,6,6,7,7,7-d7 Acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.23 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).
As a certified reference material (CRM), Heptanoic-5,5,6,6,7,7,7-d7 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.
