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 1-(3-Chlorophenyl)-3-(1-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)urea.
CATO supplies 1-(3-Chlorophenyl)-3-(1-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)urea (CAS 1396856-26-0), a certified reference material (molecular formula C20H20ClN5O2, MW 397.86 g/mol) for analytical method development and quality control.
Structurally, 1-(3-Chlorophenyl)-3-(1-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)urea (C20H20ClN5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 397.86 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), 1-(3-Chlorophenyl)-3-(1-(3-(pyridin-4-yl)-1,2,4-oxadiazol-5-yl)cyclohexyl)urea 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.
