Chemical Structure

Urethane-D5 CAS 73962-07-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 94.12 g/mol gives Urethane-D5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Urethane-D5 (CAS 73962-07-9) is a high-purity analytical reference standard with the molecular formula C3H2D5NO2 and a molecular weight of 94.12 g/mol.

Owing to deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Urethane-D5 is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 94.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Urethane-D5 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.
