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 3-Mesityl-4,5,6,7-tetrahydrocycloocta[d]isoxazole.
CATO supplies 3-Mesityl-4,5,6,7-tetrahydrocycloocta[d]isoxazole (CAS 88409-20-5), a certified reference material (molecular formula C18H21NO, MW 267.37 g/mol) for analytical method development and quality control.
3-Mesityl-4,5,6,7-tetrahydrocycloocta[d]isoxazole (C18H21NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
