5,5-Dimethyl-3',3a',4',6a'-tetrahydro-1'H-spiro[[1,3]dioxane-2,2'-pentalene] CAS 92007-41-5 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 5,5-Dimethyl-3',3a',4',6a'-tetrahydro-1'H-spiro[[1,3]dioxane-2,2'-pentalene].

CATO supplies 5,5-Dimethyl-3',3a',4',6a'-tetrahydro-1'H-spiro[[1,3]dioxane-2,2'-pentalene] (CAS 92007-41-5), a certified reference material (molecular formula C13H20O2, MW 208.30 g/mol) for analytical method development and quality control.

5,5-Dimethyl-3',3a',4',6a'-tetrahydro-1'H-spiro[[1,3]dioxane-2,2'-pentalene] (C13H20O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
