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 Fmoc-(s)-3-amino-3-(4-chlorophenyl)propionic acid.
Fmoc-(s)-3-amino-3-(4-chlorophenyl)propionic acid (CAS 479064-91-0) is a high-purity analytical reference standard with the molecular formula C24H20ClNO4 and a molecular weight of 421.87 g/mol.
Structurally, Fmoc-(s)-3-amino-3-(4-chlorophenyl)propionic acid (C24H20ClNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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 421.87 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), Fmoc-(s)-3-amino-3-(4-chlorophenyl)propionic acid 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.
