Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 401.88 g/mol gives TNP-470 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
TNP-470 (CAS 129298-91-5), molecular formula C19H28ClNO6 and molecular weight 401.88 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, TNP-470 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 401.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), TNP-470 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.
