Chemical Structure
Description
The occurrence of Verlukast-d is closely related to deuterium isotope labeling, a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Verlukast-d (CAS 153698-86-3), molecular formula C26H21D6ClN2O3S2 and molecular weight 521.12 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Verlukast-d (C26H21D6ClN2O3S2) contains deuterium isotope labeling, a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 521.12 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Verlukast-d under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
