Chemical Structure
Description
3-Hydroxy-2-(5-nitro-2-oxopyridin-1(2H)-yl)propyl 4-chlorobenzoate (CAS 400076-76-8), molecular formula C15H13ClN2O6 and molecular weight 352.73 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-Hydroxy-2-(5-nitro-2-oxopyridin-1(2H)-yl)propyl 4-chlorobenzoate (C15H13ClN2O6) 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 352.73 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), 3-Hydroxy-2-(5-nitro-2-oxopyridin-1(2H)-yl)propyl 4-chlorobenzoate 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.
