3,3-Diethyl-1-(methylsulfonyl)cyclobutane-1-carboxylic acid CAS 1478688-32-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3,3-Diethyl-1-(methylsulfonyl)cyclobutane-1-carboxylic acid.

CATO supplies 3,3-Diethyl-1-(methylsulfonyl)cyclobutane-1-carboxylic acid (CAS 1478688-32-2), a certified reference material (molecular formula C10H18O4S, MW 234.31 g/mol) for analytical method development and quality control.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3,3-Diethyl-1-(methylsulfonyl)cyclobutane-1-carboxylic acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.31 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.
