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 4-[4-(Propan-2-yloxy)phenoxy]benzene-1-sulfonyl chloride.
4-[4-(Propan-2-yloxy)phenoxy]benzene-1-sulfonyl chloride (CAS 946386-81-8), molecular formula C15H15ClO4S and molecular weight 326.80 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-[4-(Propan-2-yloxy)phenoxy]benzene-1-sulfonyl chloride (C15H15ClO4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 326.80 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-[4-(Propan-2-yloxy)phenoxy]benzene-1-sulfonyl 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.
