Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Phenyl-6,7-dihydrobenzo[b]pyrrolo[1,2-d][1,4]thiazepin-7-ol (CAS 85725-93-5), molecular formula C18H15NOS and molecular weight 293.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Phenyl-6,7-dihydrobenzo[b]pyrrolo[1,2-d][1,4]thiazepin-7-ol (C18H15NOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 293.38 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
