Chemical Structure

Dotinurad Intermediate 2 CAS 37908-97-7 chemical structure

Description

The occurrence of Dotinurad Intermediate 2 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Dotinurad Intermediate 2 (CAS 37908-97-7), molecular formula C8H6Cl2O3 and molecular weight 221.04 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C8H6Cl2O3, Dotinurad Intermediate 2 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Dotinurad Intermediate 2 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.
