Chemical Structure

Thiosemicarbazide CAS 79-19-6 chemical structure

Description

As a certified reference material (CRM), Thiosemicarbazide 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.

Thiosemicarbazide (CAS 79-19-6) is a high-purity analytical reference standard with the molecular formula CH5N3S and a molecular weight of 91.14 g/mol.

The molecular framework of Thiosemicarbazide (CH5N3S) is characterized by sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
