Chemical Structure

Methyl 3-methyleneheptanoate CAS 746622-30-0 chemical structure

Description

The occurrence of Methyl 3-methyleneheptanoate 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.

CATO supplies Methyl 3-methyleneheptanoate (CAS 746622-30-0), a certified reference material (molecular formula C9H16O2, MW 156.22 g/mol) for analytical method development and quality control.

Structurally, Methyl 3-methyleneheptanoate (C9H16O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 156.22 g/mol, it falls into the medium-molecular-weight range.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
