Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 277.40 g/mol gives Terbucarb distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Terbucarb (CAS 1918-11-2) is a high-purity analytical reference standard with the molecular formula C17H27NO2 and a molecular weight of 277.40 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Terbucarb is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 277.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Terbucarb 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.
