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.
Pentanoic-3,3-d2 Acid (CAS 83741-74-6), molecular formula C5H8D2O2 and molecular weight 104.14 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, Pentanoic-3,3-d2 Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
