Chemical Structure

Trimethyl Orthoacetate CAS 1445-45-0 chemical structure

Description

The occurrence of Trimethyl Orthoacetate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Trimethyl Orthoacetate (CAS 1445-45-0), molecular formula C5H12O3 and molecular weight 120.15 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Trimethyl Orthoacetate (C5H12O3) 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 120.15 g/mol, it falls into the low-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.
