Chemical Structure
Description
The occurrence of 3-Methylcrotonic acid-d6 is closely related to deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Methylcrotonic acid-d6 (CAS 21386-86-7), a certified reference material (molecular formula C5H2D6O2, MW 106.15 g/mol) for analytical method development and quality control.
Structurally, 3-Methylcrotonic acid-d6 (C5H2D6O2) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 106.15 g/mol, it falls into the low-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
