Chemical Structure
Description
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.
2,4,4-Trimethyl-3-oxopentanoic acid (CAS 53333-24-7), molecular formula C8H14O3 and molecular weight 158.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,4,4-Trimethyl-3-oxopentanoic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
