Chemical Structure

4-Hydrazono-3,4-dihydrothieno[3,2-d]pyrimidine CAS 16229-26-8 chemical structure

Description

As a certified reference material (CRM), 4-Hydrazono-3,4-dihydrothieno[3,2-d]pyrimidine 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.

CATO supplies 4-Hydrazono-3,4-dihydrothieno[3,2-d]pyrimidine (CAS 16229-26-8), a certified reference material (molecular formula C6H6N4S, MW 166.20 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 4-Hydrazono-3,4-dihydrothieno[3,2-d]pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
