Chemical Structure

3,3-Dimethylbutanoic Acid-d9 CAS CATO-C3D-5559 chemical structure

Description

Owing to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 3,3-Dimethylbutanoic Acid-d9 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 125.21 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).

3,3-Dimethylbutanoic Acid-d9 (CAS CATO-C3D-5559), molecular formula C6H3D9O2 and molecular weight 125.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
