Chemical Structure

3-Methyl-naphthalene-1-carboxylic acid ethyl ester CAS 92495-90-4 chemical structure

Description

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.

3-Methyl-naphthalene-1-carboxylic acid ethyl ester (CAS 92495-90-4) is a high-purity analytical reference standard with the molecular formula C14H14O2 and a molecular weight of 214.26 g/mol.

Structurally, 3-Methyl-naphthalene-1-carboxylic acid ethyl ester (C14H14O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 214.26 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
