Chemical Structure

Bis(2-ethylhexyl) glutarate CAS 21302-20-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 356.54 g/mol gives Bis(2-ethylhexyl) glutarate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bis(2-ethylhexyl) glutarate (CAS 21302-20-5) is a high-purity analytical reference standard with the molecular formula C21H40O4 and a molecular weight of 356.54 g/mol.

Structurally, Bis(2-ethylhexyl) glutarate (C21H40O4) 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 356.54 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
