Chemical Structure

Isochroman-1-carboxylic Acid CAS 13328-85-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 178.18 g/mol gives Isochroman-1-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Isochroman-1-carboxylic Acid (CAS 13328-85-3), a certified reference material (molecular formula C10H10O3, MW 178.18 g/mol) for analytical method development and quality control.

Structurally, Isochroman-1-carboxylic Acid (C10H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 178.18 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.

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.
