Chemical Structure

Bis(2-ethoxyethyl) Phthalate CAS 605-54-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 310.34 g/mol gives Bis(2-ethoxyethyl) Phthalate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bis(2-ethoxyethyl) Phthalate (CAS 605-54-9), a certified reference material (molecular formula C16H22O6, MW 310.34 g/mol) for analytical method development and quality control.

Structurally, Bis(2-ethoxyethyl) Phthalate (C16H22O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 310.34 g/mol, it falls into the moderately-high-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), Bis(2-ethoxyethyl) Phthalate 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.
