Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 276.28 g/mol gives Triethyl Citrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Triethyl Citrate (CAS 77-93-0) is a high-purity analytical reference standard with the molecular formula C12H20O7 and a molecular weight of 276.28 g/mol.
Structurally, Triethyl Citrate (C12H20O7) 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 276.28 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Triethyl Citrate 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.
