CATO supplies 1014104-43-8 (5E)-1,2,3,4,10,11-Hexahydro-5H-spiro[benzo[c]pyrano[3,2-g]chromene-9,1'-cyclohexan]-5-one oxime MFCD09845298 (CAS 1014104-43-8), a certified reference material (molecular formula C21H25NO3, MW 339.43 g/mol) for analytical method development and quality control.
Structurally, 1014104-43-8 (5E)-1,2,3,4,10,11-Hexahydro-5H-spiro[benzo[c]pyrano[3,2-g]chromene-9,1'-cyclohexan]-5-one oxime MFCD09845298 (C21H25NO3) contains a steroid core, an amide 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 339.43 g/mol, it falls into the moderately-high-molecular-weight range. 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.
