Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-((2S,3S)-3-(3-Cyanophenyl)-4-(4-ethoxyphenyl)butan-2-yl)-2-methyl-2-((5-methylpyridin-2-yl)oxy)propanamide.
N-((2S,3S)-3-(3-Cyanophenyl)-4-(4-ethoxyphenyl)butan-2-yl)-2-methyl-2-((5-methylpyridin-2-yl)oxy)propanamide (CAS 945850-36-2) is a high-purity analytical reference standard with the molecular formula C29H32[18F]N3O3 and a molecular weight of 488.58 g/mol.
Structurally, N-((2S,3S)-3-(3-Cyanophenyl)-4-(4-ethoxyphenyl)butan-2-yl)-2-methyl-2-((5-methylpyridin-2-yl)oxy)propanamide (C29H32[18F]N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 488.58 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-((2S,3S)-3-(3-Cyanophenyl)-4-(4-ethoxyphenyl)butan-2-yl)-2-methyl-2-((5-methylpyridin-2-yl)oxy)propanamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
