[1,2,5]Thiadiazolo[3,4-d]pyrimidin-7-amine CAS 2829-57-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [1,2,5]Thiadiazolo[3,4-d]pyrimidin-7-amine.

[1,2,5]Thiadiazolo[3,4-d]pyrimidin-7-amine (CAS 2829-57-4), molecular formula C4H3N5S and molecular weight 153.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, [1,2,5]Thiadiazolo[3,4-d]pyrimidin-7-amine (C4H3N5S) contains a nitrile group, sulfur-containing functionality. 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 153.17 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), [1,2,5]Thiadiazolo[3,4-d]pyrimidin-7-amine 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.
