Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2,3,4,10,11-Hexahydro-5h-spiro[benzo[c]pyrano[3,2-g]chromene-9,1'-cyclohexane]-5-thione.
CATO supplies 1,2,3,4,10,11-Hexahydro-5h-spiro[benzo[c]pyrano[3,2-g]chromene-9,1'-cyclohexane]-5-thione (CAS 919748-91-7), a certified reference material (molecular formula C21H24O2S, MW 340.48 g/mol) for analytical method development and quality control.
Structurally, 1,2,3,4,10,11-Hexahydro-5h-spiro[benzo[c]pyrano[3,2-g]chromene-9,1'-cyclohexane]-5-thione (C21H24O2S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 340.48 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).
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.
CATO manufactures 1,2,3,4,10,11-Hexahydro-5h-spiro[benzo[c]pyrano[3,2-g]chromene-9,1'-cyclohexane]-5-thione under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
