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 1,2:4,5-Biscyclohexylidene DL-myo-Inositol.
1,2:4,5-Biscyclohexylidene DL-myo-Inositol (CAS 104873-71-4), molecular formula C18H28O6 and molecular weight 340.41 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, 1,2:4,5-Biscyclohexylidene DL-myo-Inositol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.41 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.
