Chemical Structure

p-Toluic acid-d3 CAS 19215-16-8 chemical structure

Description

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

p-Toluic acid-d3 (CAS 19215-16-8) is a high-purity analytical reference standard with the molecular formula C8H5D3O2 and a molecular weight of 139.17 g/mol.

Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, p-Toluic acid-d3 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.17 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).

As a certified reference material (CRM), p-Toluic acid-d3 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.
