Chemical Structure
Description
The occurrence of 3-chloro-4-methyl-2-oxo-2H-chromen-7-yl 3,3-dimethylbutan-2-yl methylphosphonate is closely related to a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-chloro-4-methyl-2-oxo-2H-chromen-7-yl 3,3-dimethylbutan-2-yl methylphosphonate (CAS 875577-99-4), a certified reference material (molecular formula C17H22ClO5P, MW 372.78 g/mol) for analytical method development and quality control.
Owing to a steroid core, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution, 3-chloro-4-methyl-2-oxo-2H-chromen-7-yl 3,3-dimethylbutan-2-yl methylphosphonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.78 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
