Chemical Structure
Description
3,4-O-Isopropylidene Clindamycin B (C20H35ClN2O5SC2H4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
3,4-O-Isopropylidene Clindamycin B (CAS CATO-C4X-1341123), molecular formula C20H35ClN2O5SC2H4O2 and molecular weight 511.07 g/mol, is a CATO reference standard with documented purity and traceability.
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.
As a certified reference material (CRM), 3,4-O-Isopropylidene Clindamycin B meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
