Sitofibrate - API Standards CAS 55902-94-8 chemical structure

Description

Sitofibrate - API Standards (CAS 55902-94-8), molecular formula C39H59ClO3 and molecular weight 611.34 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, Sitofibrate - API Standards is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 611.34 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.

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), Sitofibrate - API Standards 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.
