Chemical Structure

DL-Leucine-d7 (iso-propyl-d7) CAS 259225-40-6 chemical structure

Description

Owing to deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, DL-Leucine-d7 (iso-propyl-d7) is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

DL-Leucine-d7 (iso-propyl-d7) (CAS 259225-40-6) is a high-purity analytical reference standard with the molecular formula C6H6D7NO2 and a molecular weight of 138.22 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), DL-Leucine-d7 (iso-propyl-d7) 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.
