Compared with other compounds in its class, the molecular weight of 361.87 g/mol gives Sigma-1 receptor precursor distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Sigma-1 receptor precursor (CAS 2448691-41-4), molecular formula C19H24ClN3O2 and molecular weight 361.87 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Sigma-1 receptor precursor is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 361.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Sigma-1 receptor precursor 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.
