Chemical Structure
Description
The occurrence of Thalidomide-O-amido-C4-NH2 (hydrochloride) is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Thalidomide-O-amido-C4-NH2 (hydrochloride) (CAS 2245697-86-1), molecular formula C19H22N4O6HCl and molecular weight 438.86 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Thalidomide-O-amido-C4-NH2 (hydrochloride) (C19H22N4O6HCl) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 438.86 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), Thalidomide-O-amido-C4-NH2 (hydrochloride) 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.
