1,5-dimethyl 2-acetylpentanedioate CAS 116981-01-2

Description

The occurrence of 1,5-dimethyl 2-acetylpentanedioate 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.

1,5-dimethyl 2-acetylpentanedioate (CAS 116981-01-2), molecular formula C9H14O5 and molecular weight 202.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,5-dimethyl 2-acetylpentanedioate (C9H14O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 202.20 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

As a certified reference material (CRM), 1,5-dimethyl 2-acetylpentanedioate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
