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 Valdecoxib Sulfonyl Chloride-13C2,15N.
Valdecoxib Sulfonyl Chloride-13C2,15N (CAS 1391051-92-5), molecular formula C14[13C]2H12Cl[15N]O3S and molecular weight 336.77 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Valdecoxib Sulfonyl Chloride-13C2,15N (C14[13C]2H12Cl[15N]O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Valdecoxib Sulfonyl Chloride-13C2,15N 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.
