Chemical Structure

Isochromane-1-acetic Acid CAS 22901-11-7 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 Isochromane-1-acetic Acid.

CATO supplies Isochromane-1-acetic Acid (CAS 22901-11-7), a certified reference material (molecular formula C11H12O3, MW 192.21 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Isochromane-1-acetic Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
