(((4-(Chloromethyl)-1,2-phenylene)bis(oxy))bis(methylene))dibenzene CAS 1699-59-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (((4-(Chloromethyl)-1,2-phenylene)bis(oxy))bis(methylene))dibenzene.

(((4-(Chloromethyl)-1,2-phenylene)bis(oxy))bis(methylene))dibenzene (CAS 1699-59-8), molecular formula C21H19ClO2 and molecular weight 338.83 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (((4-(Chloromethyl)-1,2-phenylene)bis(oxy))bis(methylene))dibenzene (C21H19ClO2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 338.83 g/mol, it falls into the moderately-high-molecular-weight range. 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), (((4-(Chloromethyl)-1,2-phenylene)bis(oxy))bis(methylene))dibenzene 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.
