Chemical Structure

Salicylic acid-13C6 CAS 1189678-81-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 144.08 g/mol gives Salicylic acid-13C6 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Salicylic acid-13C6 (CAS 1189678-81-6), a certified reference material (molecular formula C[13C]6H6O3, MW 144.08 g/mol) for analytical method development and quality control.

The molecular framework of Salicylic acid-13C6 (C[13C]6H6O3) is characterized by a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
