Chemical Structure

Octadecanoic acid, hydroxy-, polymer with 2-(chloromethyl)oxirane and 4,4'-(1-methylethylidene)bis[phenol] CAS 79771-14-5 chemical structure

Description

The occurrence of Octadecanoic acid, hydroxy-, polymer with 2-(chloromethyl)oxirane and 4,4'-(1-methylethylidene)bis[phenol] is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Octadecanoic acid, hydroxy-, polymer with 2-(chloromethyl)oxirane and 4,4'-(1-methylethylidene)bis[phenol] (CAS 79771-14-5) is a high-purity analytical reference standard with the molecular formula C18H36O3C15H16O2C3H5ClO and a molecular weight of 621.30 g/mol.

The molecular framework of Octadecanoic acid, hydroxy-, polymer with 2-(chloromethyl)oxirane and 4,4'-(1-methylethylidene)bis[phenol] (C18H36O3C15H16O2C3H5ClO) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Octadecanoic acid, hydroxy-, polymer with 2-(chloromethyl)oxirane and 4,4'-(1-methylethylidene)bis[phenol] 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.
