Chemical Structure

But-2-ynoic-d3 acid CAS 1375453-30-7 chemical structure

Description

But-2-ynoic-d3 acid (CAS 1375453-30-7), molecular formula C4HD3O2 and molecular weight 87.09 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, But-2-ynoic-d3 acid is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 87.09 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), But-2-ynoic-d3 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.
