Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 451.34 g/mol gives 4-DAMP distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-DAMP (CAS 1952-15-4) is a high-purity analytical reference standard with the molecular formula C20H23NO2CH3I and a molecular weight of 451.34 g/mol.
Structurally, 4-DAMP (C20H23NO2CH3I) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 451.34 g/mol, it falls into the moderately-high-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.
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.
