Chemical Structure

(Cys18)-Atrial Natriuretic Factor (4-18) amide (mouse, rabbit, rat) CAS 111863-73-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Cys18)-Atrial Natriuretic Factor (4-18) amide (mouse, rabbit, rat).

CATO supplies (Cys18)-Atrial Natriuretic Factor (4-18) amide (mouse, rabbit, rat) (CAS 111863-73-1), a certified reference material (molecular formula C64H107N25O19S2, MW 1594.84 g/mol) for analytical method development and quality control.

Structurally, (Cys18)-Atrial Natriuretic Factor (4-18) amide (mouse, rabbit, rat) (C64H107N25O19S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 24.0, corresponding to approximately 24 ring(s) or double-bond equivalent(s). With a molecular weight of 1594.84 g/mol, it falls into the high-molecular-weight range. 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).

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.
