Chemical Structure

6-Methyl-4-oxo-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid CAS 33448-17-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-Methyl-4-oxo-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid.

CATO supplies 6-Methyl-4-oxo-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid (CAS 33448-17-8), a certified reference material (molecular formula C12H12O3, MW 204.22 g/mol) for analytical method development and quality control.

Structurally, 6-Methyl-4-oxo-1,2,3,4-tetrahydronaphthalene-2-carboxylic acid (C12H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 204.22 g/mol, it falls into the medium-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
