Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 311.44 g/mol gives Dosulepin Impurity A distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dosulepin Impurity A (CAS 42046-35-5), molecular formula C19H21NOS and molecular weight 311.44 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dosulepin Impurity A (C19H21NOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. 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 311.44 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures Dosulepin Impurity A 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.
