Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 225.28 g/mol gives (R)-Terbutaline hemisulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-Terbutaline hemisulfate (CAS 37394-31-3) is a high-purity analytical reference standard with the molecular formula C12H19NO3 and a molecular weight of 225.28 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (R)-Terbutaline hemisulfate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.28 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 (R)-Terbutaline hemisulfate 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.
