Chemical Structure

(R)-2-Cl-Phox-Bn CAS 2634687-74-2 chemical structure

Description

Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution, (R)-2-Cl-Phox-Bn is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 455.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

(R)-2-Cl-Phox-Bn (CAS 2634687-74-2) is a high-purity analytical reference standard with the molecular formula C28H23ClNOP and a molecular weight of 455.92 g/mol.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
