Chemical Structure
Description
The occurrence of rac 8α-[Δ-5(10)]-Norgestrel is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies rac 8α-[Δ-5(10)]-Norgestrel (CAS 5541-87-7), a certified reference material (molecular formula C21H28O2, MW 312.45 g/mol) for analytical method development and quality control.
Based on its molecular formula C21H28O2, rac 8α-[Δ-5(10)]-Norgestrel contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 312.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
