Chemical Structure
Description
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.
CATO supplies (E)-[(1-Chloro-3,4-dihydronaphthalen-2-yl)methylidene]amino N-(4-methylphenyl)carbamate (CAS 477887-98-2), a certified reference material (molecular formula C19H17ClN2O2, MW 340.80 g/mol) for analytical method development and quality control.
Structurally, (E)-[(1-Chloro-3,4-dihydronaphthalen-2-yl)methylidene]amino N-(4-methylphenyl)carbamate (C19H17ClN2O2) contains a steroid core, an amide group, 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 340.80 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.
As a certified reference material (CRM), (E)-[(1-Chloro-3,4-dihydronaphthalen-2-yl)methylidene]amino N-(4-methylphenyl)carbamate 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.
