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-ethylphenyl)(thien-2-yl)methylamine hydrochloride.
(4-ethylphenyl)(thien-2-yl)methylamine hydrochloride (CAS 1172929-94-0), molecular formula C13H15NSHCl and molecular weight 253.79 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4-ethylphenyl)(thien-2-yl)methylamine hydrochloride (C13H15NSHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 253.79 g/mol, it falls into the medium-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-ethylphenyl)(thien-2-yl)methylamine hydrochloride 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.
