Chemical Structure

P-Xylylene diacetate CAS 14720-70-8 chemical structure

Description

Structurally, P-Xylylene diacetate (C8H10O2C2H4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 198.22 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).

P-Xylylene diacetate (CAS 14720-70-8) is a high-purity analytical reference standard with the molecular formula C8H10O2C2H4O2 and a molecular weight of 198.22 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
