2-Methyl-1,4-naphthalenediol CAS 481-85-6

Description

Compared with other compounds in its class, the molecular weight of 174.20 g/mol gives 2-Methyl-1,4-naphthalenediol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Methyl-1,4-naphthalenediol (CAS 481-85-6), molecular formula C11H10O2 and molecular weight 174.20 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Methyl-1,4-naphthalenediol (C11H10O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.

As a certified reference material (CRM), 2-Methyl-1,4-naphthalenediol 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.
