Chemical Structure

Tetramethyl 5,5,9-trimethyl-5,6-dihydrospiro[thiopyrano[2,3-c]quinoline-1,2'-[1,3]dithiole]-2,3,4',5'-tetracarboxylate CAS 258267-23-1 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 Tetramethyl 5,5,9-trimethyl-5,6-dihydrospiro[thiopyrano[2,3-c]quinoline-1,2'-[1,3]dithiole]-2,3,4',5'-tetracarboxylate.

CATO supplies Tetramethyl 5,5,9-trimethyl-5,6-dihydrospiro[thiopyrano[2,3-c]quinoline-1,2'-[1,3]dithiole]-2,3,4',5'-tetracarboxylate (CAS 258267-23-1), a certified reference material (molecular formula C25H25NO8S3, MW 563.66 g/mol) for analytical method development and quality control.

Structurally, Tetramethyl 5,5,9-trimethyl-5,6-dihydrospiro[thiopyrano[2,3-c]quinoline-1,2'-[1,3]dithiole]-2,3,4',5'-tetracarboxylate (C25H25NO8S3) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 563.66 g/mol, it falls into the moderately-high-molecular-weight range. 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.
