Chemical Structure

间苯三酚杂质8 CAS 84212-55-5 chemical structure

Description

The occurrence of 间苯三酚杂质8 is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

间苯三酚杂质8 (CAS 84212-55-5) is a certified pharmaceutical impurity reference standard with the molecular formula C17H20 and a molecular weight of 224.34 g/mol.

Owing to a polycyclic aromatic system, 间苯三酚杂质8 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 224.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), 间苯三酚杂质8 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.
