(<I>R,R</I>)-<I>N,N′</I>-bis(3,5-di-tert-butylsalicylene)-1,2-cyclohexanediamine Chromium(III) chloride CAS 164931-83-3 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 (<I>R,R</I>)-<I>N,N′</I>-bis(3,5-di-tert-butylsalicylene)-1,2-cyclohexanediamine Chromium(III) chloride.

(<I>R,R</I>)-<I>N,N′</I>-bis(3,5-di-tert-butylsalicylene)-1,2-cyclohexanediamine Chromium(III) chloride (CAS 164931-83-3) is a high-purity analytical reference standard with the molecular formula C36H64ClCrN2O2 and a molecular weight of 644.35 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (<I>R,R</I>)-<I>N,N′</I>-bis(3,5-di-tert-butylsalicylene)-1,2-cyclohexanediamine Chromium(III) chloride is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 644.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), (<I>R,R</I>)-<I>N,N′</I>-bis(3,5-di-tert-butylsalicylene)-1,2-cyclohexanediamine Chromium(III) chloride 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.
