Description
CATO manufactures Chlorambucil EP Impurity C 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.
Chlorambucil EP Impurity C (CAS CATO-C4X-35541) is a certified pharmaceutical impurity reference standard with the molecular formula C18H27Cl3NO6P and a molecular weight of 490.74 g/mol.
Owing to a steroid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution, Chlorambucil EP Impurity C is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 490.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
