1,2,3-Trimethylbenzene CAS 526-73-8

Description

The occurrence of 1,2,3-Trimethylbenzene is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,2,3-Trimethylbenzene (CAS 526-73-8), molecular formula C9H12 and molecular weight 120.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1,2,3-Trimethylbenzene (C9H12) is characterized by an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its non-polar molecular character, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

CATO manufactures 1,2,3-Trimethylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
