Chemical Structure
Description
Trimethyl orthovalerate (CAS 13820-09-2), molecular formula C8H18O3 and molecular weight 162.23 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Trimethyl orthovalerate (C8H18O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 162.23 g/mol, it falls into the medium-molecular-weight range.
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.
