1-({4-chloro-5-phenylthieno[2,3-d]pyrimidin-2-yl}methyl)piperidine CAS 731815-64-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-({4-chloro-5-phenylthieno[2,3-d]pyrimidin-2-yl}methyl)piperidine.

1-({4-chloro-5-phenylthieno[2,3-d]pyrimidin-2-yl}methyl)piperidine (CAS 731815-64-8), molecular formula C18H18ClN3S and molecular weight 343.87 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-({4-chloro-5-phenylthieno[2,3-d]pyrimidin-2-yl}methyl)piperidine (C18H18ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 343.87 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), 1-({4-chloro-5-phenylthieno[2,3-d]pyrimidin-2-yl}methyl)piperidine 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.
